Question

Please Help! The figure below shows parallel lines cut by a transversal:

Which statement is true about ∠7 and ∠8?


1. ∠7 and ∠8 are supplementary because they are a pair of corresponding angles.

2. ∠7 and ∠8 are complementary because they are a pair of adjacent angles on a straight line.

3. ∠7 and ∠8 are congruent because they are a pair of adjacent angles on a straight line.

4. ∠7 and ∠8 are supplementary because they are a pair of adjacent angles that form a straight line.

Answer 1

The answer is choice 4, they add up to 180°

Answer 2

Option 4.

Explanation:

When two adjacent angles are formed at a point on a line so that sum of their measures is 180°, angles are called as supplementary to each other.

In the figure attached, ∠7 and ∠8 are supplementary because they are a pair of adjacent angles that form a straight line.

Option 4. is the right answer.
