WebTriangle XYZ is isosceles. The measure of the vertex angle, Y, is twice the measure of a base angle. What is true about triangle XYZ? Select three options. A. Angle Y is a right angle. B. The measure of angle Z is 45°. E. The perpendicular bisector of line XZ creates two smaller isosceles triangles. WebLet ABC be the isosceles triangle with apex C and base AB. From midpoint M of leg BC and from apex C, drop perpendicular lines onto AB (→ G and H). Setting CA = CB = 4x, you can conclude from the 30°-60°-90° triangle CAH that. CH = 2x. AH = 2x∙√3. Since M is the midpoint of BC, we also have. MG = CH/2 = x. HG = AH/2 = x∙√3. AG = 3x ...
