Incenter angle formula
WebJun 15, 2024 · If Y is on the angle bisector, then XY = YZ and both segments need to be perpendicular to the sides of the angle. From the markings we know ¯ XY ⊥ → WX and ¯ ZY ⊥ → WZ. Second, XY = YZ = 6. So, yes, Y is on the angle bisector of ∠XWZ. Example 4.21.4 → MO is the angle bisector of ∠LMN. Find the measure of x.
