2.1-2.4 Review!It’s Go Time!
Answer the question:
What is the next letter in the sequence?D, H, L, P, . . .
A Q C S B R D T
Draw a Counterexample “If two rays have the same endpoint, then they are opposite rays.”
Answer the question!Identify the hypothesis of the conditional
statement “Two angles are complementary if the sum of their measures is 90 degrees.”
A ifB Two angles are complementaryC the sum of their measures is 90
degreesD Two angles are complementary if the
sum of their measures is 90 degrees.
Multiple ChoiceChange the following statement into a conditionalstatement:
“The sum of two odd numbers is even.”A If two even numbers are added, then their
sum is even.B If an even and odd number are added, then their sum is even.C If two even numbers are multiplied, then their product is oddD If two odd numbers are added, then their
product is even.
Choose Wisely!What is the inverse of the statement“If two coplanar lines do not intersect, then they are parallel”?
A If two coplanar lines do not intersect, then they are not parallel.
B If two coplanar lines intersect, then they are not parallel.
C If two lines are parallel, then they are coplanar and do not intersect.
D If two coplanar lines are not parallel, then they intersect.
SyllogismWhich conjecture is valid by the Law of
Syllogism for the following scenario?“If Joe buys Nancy a card, he will give it to her. If Nancy is having a birthday, then Joe will buy her a card.”
A If Nancy is having a birthday, then Joe will give her a card.
B If Joe buys Nancy a card, then she is having a birthday.
C If Joe gives Nancy a card, then he bought the card.
D If Joe gives Nancy a card, then she is having a birthday.
Valid or InvalidIf you study for the test, then you will
get an A. You get an A. Therefore, you studied for the test.
Valid or InvalidIf I am cool, then I love Geometry!I am cool.Therefore, I love Geometry.
What can you Conclude?If Maria does not study, then she fails
her test. If Maria fails her test, then she will be grounded. If Maria is grounded, then she will not be able to go to the movies with her friends. If Maria cannot go to the movies with her friends, then Sally will steal Maria’s friend.
Maria does not study.
Fill in the BlanksIf two planes intersect, then their
intersection is a
A line consists of at least points.
Two angles that form right angles
are called .
Which conjecture is true?A. An even number plus 3 is always
even.B. An even number plus 3 is always
prime.C. An even number plus 3 is always
odd.D. A prime number plus 3 is always
even.
Which law of logic allows the conclusion?For the past three weeks, the math team
has been meeting on Tuesday mornings. Sam concludes that the math team will meet this Tuesday morning.
A. Law of DetachmentB. Law of SyllogismC. Inductive ReasoningD. Deductive Reasoning
What is the converse?“If there are clouds in the sky, then it is
raining.”A. If it is raining, then there are clouds in the
sky.B. If it is not raining, then there are clouds in
the sky.C. If it is raining, then there are no clouds in the
sky.D. If it is not raining, then there are no clouds in
the sky.
How would you write the following statement symbolically?Let p represent “B is between A and
C”Let q represent “A, B, and C are
collinear”
“If B is not between A and C, then A, B, and C are not
collinear.”
True or False?If two odd numbers are multiplied, then the product is an odd number.
What is the next item in the pattern?
-1, 2, -4, 8, …A.-16B.-4C.4D.16
Write as a conditional statement in “if, then” form“A number divisible by 10 is divisible by 5.”
Use the Transitive Prop to complete the statement
If AB = CD and CD = EF, then …
