Pythagorean Theorem
In a right triangle,
a2 + b2 = c2
a and b are the legs (shorter sides that form the right angle)
c is the hypotenuse (longest side, opposite the right ∠)

a) (5, 13) & (9, 10) b) ( –2 , 6) & ( –7 , –6)
Use the Pythagorean Theorem to find the distance between the two points.

Congruent Angles
Congruent angles are angles that have the same measure.

Angle Bisector
An angle bisector is a ray that divides an angle into two congruent angles.

Jigsaw Activity• How it works:
– Each team will be assigned to one type of angle pair.– As a team, research your angle pair.
• No more than 2 electronic devices per group
– Fill in the space for your angle pair with its definition and a diagram.
– EVERYONE Be prepared to explain your angle pair to others.

Jigsaw Activity
• Teams 7 : adjacent angles• Teams 1 & 2: linear pair (compare 2 sources)• Teams 3 & 6: vertical angles• Teams 4 & 5: complementary and supplementary
angles
• You have 7 minutes to research your angle pair and fill in the graphic organizer with its definition and a diagram.

Jigsaw Activity
When I tell you to, you will move to your new group* and do the following:
• Teach your classmates about your angle pair.– Make sure everyone understands.
• Complete your graphic organizers with the information you have learned.– Make sure you have a definition and a diagram for
each angle pair.
*New group assignments on next slide.
