Question

use the figure. identify the linear pair(s) that include ∠7. ∠7 and ∠6 ∠7 and ∠8 ∠7 and ∠9 ∠7 and ∠5

Explanation:

Step1: Recall linear - pair definition

A linear pair of angles is a pair of adjacent angles formed when two lines intersect. The sum of the measures of angles in a linear pair is 180 degrees.

Step2: Analyze angles around the intersection

In the given figure, ∠7 and ∠8 are adjacent angles and they form a straight - line. So, they are a linear pair. ∠7 and ∠6 are vertical angles. ∠7 and ∠9 are vertical angles. ∠7 and ∠5 are neither vertical nor linear - pair angles.

Answer:

∠7 and ∠8
