!! will medal !! Triangle XYZ is isosceles. The measure of the vertex angle, Y, is twice the measure of a base angle. What is true about triangle XYZ? Check all that apply. Angle Y is a right angle. The measure of angle Z is 45°. The measure of angle X is 36°. The measure of the vertex angle is 72°. The perpendicular bisector of XZ creates two smaller isosceles triangles.

Isosceles means that two of the sides are the same length and also two of the angles are the same length.
