Question

how many right angles does perpendicular bisector $overline{mn}$ create with $overline{kl}$? (1 point)

Explanation:

Step1: Recall definition of perpendicular bisector

A perpendicular bisector of a line segment is perpendicular to the segment, meaning it forms right - angles with the segment.

Step2: Determine number of right - angles

When a line is perpendicular to another line, it forms 4 right - angles at the intersection point. Here, $\overline{MN}$ is the perpendicular bisector of $\overline{KL}$, and they intersect at point $O$. So, 4 right - angles are formed.

Answer:

4
