Question

The figure below shows two parallel lines cut by a transversal:

Which statement is true about ∠1 and ∠2?

A: They add up to 90 degrees, because they are a pair of complementary angles.
B: They add up to 180 degrees, because they are a pair of complementary angles.
C: They add up to 180 degrees, because they are a pair of supplementary angles.
D: They add up to 90 degrees, because they are a pair of supplementary angles.

Answer 1

Answer:

C: They add up to 180 degrees, because they are a pair of supplementary angles

Step-by-step explanation:

<1 and <2 add up to 180 degrees, so they are supplementary angles.

Complementary angles add up to 90 degrees.
