1. name a pair of vertical angles. 2. name a pair of complementary angles. 3. name a pair of supplementary angles.

Part 1) m<AEB=m<DEF

Part 2)

Part 3)

Step-by-step explanation:

Part 1)

we know that

Vertical Angles are the congruent angles opposite each other when two lines cross

so

In this problem

m<AEB=m<DEF-----> by vertical angles

Part 2)

we know that

If the sum of two angles is equal to then the angles are complementary

In this problem

-----> by complementary angles

Part 3)

we know that

If the sum of two angles is equal to then the angles are supplementary

In this problem

-----> by supplementary angles

a. 74 degrees

step-by-step explanation:

because the lines through the side and the box in the corners shows that these are congruent triangles and since they are mirrored the 37 degrees is also mirrored so the answer is 37 * 2 which is 74.
