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

0.02

step-by-step explanation:

time of 9 192 631 770 periods of the radiation corresponding to the transition between the 2 hyperfine levels of the ground state of the caesium 133 atom at 0 k (but other seconds are sometimes used in astronomy)

where are the graphs?
