Question

4.) When lines are parallel, which two types of angle pairs formed by a transversal are

Supplementary?

Answer 1

Co - interior angles

Explanation:

Supplementary angles are those angles which sum to 180°.

Co- interior angles are the angles which sum to 180°, and they are angles on the interior site of two parallels enclosed by transversal.

In the figure drawn, we can see r||m and p is the transversal. Here, <1 and <2 are supplementary or co -interior angles

• <1+<2 = 180°
