Question

1. if jh is the perpendicular bisector of (overline{gi}), what is ji? 30 15 42 21

Explanation:

Step1: Recall property of perpendicular bisector

A point on the perpendicular bisector of a line - segment is equidistant from the endpoints of the line - segment.
Since JH is the perpendicular bisector of GI, and J is a point on JH, we have JG = JI.

Step2: Identify the length of JG

From the figure, we can see that JG = 21.
Since JG = JI, then JI = 21.

Answer:

21
