If JH is the perpendicular bisector of GI, what is JI ?

If JH Is The Perpendicular Bisector Of GI What Is JI class=

Sagot :

Length of segment JI is: C. 21.

Recall:

A perpendicular bisector is a segment that divides a segment into equal halves.

Thus:

JH divides GI into GH and HI

Therefore:

[tex]GH = HI = 15[/tex]

Also, since JH in right triangle JHG = JH in right triangle JHI, therefore:

the third side, GJ in right triangle JHG, will equal the third side, JI in right triangle JHI.

GJ = JI = 21

Therefore, JI is 21.
