4. Give two examples of vertically opposite angles in your surroundings.
5. In the given figure write: E D
(i) Five pairs of adjacent angles.
(ii) Four pairs of linear pair of angles.
(iii) Two pairs of Vertically
Opposite angles.
A O B

6. Give two examples of linear pair of angles.
DAY- 3
7. Solve the following as done in example:
Example: C D
If ∠AOC = 35° , Find other angles.
(2x+1)°
Solution: x°
A O B
Since ∠AOC, ∠BOD and ∠COD forms straight angle.
Therefore ∠AOC + ∠COD +∠BOD = 180°
i.e. 35° + (2x+1)° +x° = 180°
i.e. 35° + 2x° +1°+x° =180°
i.e. 3x° + 36° = 180°
i.e. 3x° = 180° - 36°
i.e. 3x° = 144°
i.e. x° = 144° ÷ 3
i.e. x° = 48°
Hence ∠BOD = x°= 48° and∠COD = (2x +1) ° = (2 x 48 +1) = (96+1) = 97°
Now solve the following:
(i) If ∠AOC = 47°, find ∠BOC. C
A O B
(ii) If ∠POR= 40° and ∠QOS = 25° , find ∠ROS.

Some important topics
The word democracy is derived from the Greek word Demos and Kratia which means
rule of the people. Democracy is therefore any system of government where people have
a choice to choose their representatives.
How did democracy originate : Democracy existed in ancient Greek city States .They
believed that all males should take part in the process of decision making .Slaves and
women had no such right. However this was possible because Greek city States were
small .In modern era democracy originated in Europe. The glorious revolution of 1688
and the bills of rights that Limited the power of the King. American war of independence
and French Revolution which popularized the ideas of liberty, equality and fraternity.
these events made a significant impact in other parts of the world when democracy
expanded from Europe to other parts of Asia and Africa. Initially only the rich and
privileged people were allowed to vote. It was a long struggle for the poor and women to
get their right to vote. Democracy focused on two features:1)People had a right to choose
their representatives and 2) curbs were placed on the power of rulers through periodic
elections.
Equality in democracy
Democracy stands much superior to any other form of government in promoting dignity
and freedom of the individual .Every individual wants to receive respect from fellow
beings .Often conflicts arise among individuals because some feel that they are not
treated with due respect. The passion for respect and freedom are the basis of democracy
.Democracies throughout the world have recognised this at least in principle. Article 15
in the Indian Constitution guarantees equality to all the citizens of the country
.Untouchability has been abolished. India is still struggling for equality. Equality means
the state of being the same especially in status, rights or opportunities.
Equal right to vote
India is a democratic country where all adults who are 18 and above are allowed to vote
irrespective of religion, caste, education level and financial status called the universal
adult franchise and is an essential component of all democracies. The two ways in which
the government has tried to implement the equality that is guaranteed in the constitution
is first through laws and second through government programs.
Enhancing human dignity
People are not discriminated on the basis of caste, colour, creed, status, class ,gender,
place of birth, religion ,property etc. The principle of equality of all citizens is
recognised. In India laws like prevention of untouchability Act 1958 and prevention of
civil rights act 1976 have been made. Reservation for scheduled caste and Scheduled
Tribes and backward classes has been provided in government jobs and educational
institutions. Scholarships for girl child and dalit children have been launched .Mid day
meal scheme in government schools has been introduced to encourage children to attend
school.
Democracy promotes dignity and freedom of an individual in the following manner:
Long struggles by women have made people realise the importance of respect and equal
treatment for women in a democracy .This realisation has helped v the disadvantaged and
discriminated castes of the society by providing them with equal status and opportunity
.Expectations from democracy also function as the criteria for judging any democratic
country. Democracy examination never gets over as it passes one test it produces another
test. As people get some benefits of democracy, they ask for more and want to make
democracy even better. The fact that people are complaining, protesting, expressing
views are testimonials to the success of democracy.

Day 4 :
Answer the following :
1) How did democracy originate?
2) How does the rule of law affect democracy?
3) Why does democracy have the best decision making mechanism?
4) What is universal adult franchise?
Check your answers :
1) Democracy existed in ancient Greek city states. they believed that all males
should take part in the process of decision making .In Modern era democracy
originated in Europe. The Glorious Revolution, American war of independence
French Revolution which popularised the ideas of liberty ,equality and fraternity.
2) In a democracy, there is a rule of law and respect for rights . All people are equal
before the eyes of law and law protects them equally. People are guaranteed
Right to Equality, think freely ,express their opinions ,form associations and
protest against unpopular actions of the government.
3) Decisions made in a democracy are best .Decision- making mechanism involves
many persons, discussions ,meetings etc. A bill goes through a lot of stages
before it becomes a law. It reduces chances of hasty and irresponsible decisions.
4) India is a democratic country where all adults who are 18 and above are allowed
to vote irrespective of religion ,caste, education level and financial status ,called
the universal adult franchise.
Day 5 :
Long answer questions :
1) Explain various forms of government with examples?
2) How does democracy accommodate diversity?
3) Does inequality exist in other countries of the world
Check your answers :
1)Various forms of government are :
1) Dictatorial form of government : In this form of government power is
concentrated in one person or a group of persons. The citizens have no role in
governance. The Dictator imposes his wish on the people example in Iraq under
Saddam Hussein.
2) Monarchial form of government: In this form of Government the power is
concentrated in a king or a monarch. It is of two types: constitutional monarchy
and absolute monarchy.
3) Parliamentary form of Government : In this form of Government the executive
is a part of the Legislature and responsible to it. If the Prime Minister loses his or
her majority, the government has to resign. India is an example of a
Parliamentary form of Government.
4) Presidential form of government : In this form of Government the president is
the chief executive and is elected for a fixed term. The legislature cannot remove
the executive. Example: the United States of America.
5) Unitary government :In this form of government a single unit of government has
jurisdiction over the entire territory. Example : the United Kingdom.
6) Federal government : In this form of Government power is divided between the
centre and the states. There is a written constitution which divides these powers
and an independent and impartial Judiciary to settle disputes between centre and
states. Example: Australia.
2)In any society people are bound to have diverse beliefs ,faiths and opinions. India
is a land of many religions, languages, cultures, castes and beliefs. The preference
of one group may clash with that of the other, leading to resentment. However
democracy offers an opportunity to this diversity to negotiate through dialogues and
discussions.
3) Inequality is not only prevalent in India, it exists even in developed states like the
US where African –Americans were denied right to equality for centuries. It was
Rosa Parks an Afro-American woman who refused to vacate herseat for a white
man in a bus on December 1st,1955 that started the Civil rights Movement in the
US led by Martin Luther King .The Civil Rights Act 1964 brought an end to
discrimination on the basis of race, religion or maternal origin.
Day 6 :
Think and discuss with your parents and friends :
Do you think India is a country based on equality? Can you find instances of inequality in
India ?(No need to write down this answer in your copy.)
