I need if EC is an altitude of triangle, AED, angle measure one equals 2X 7, an angle measure two equals 3X 13, find an angle measure one and angle measure two help with this question. The question is (if you cant see the picture well) : ANALYZE Determine whether the statement is sometimes, always, or never true. Justify your argument using a counterexample or proof. In an isosceles triangle, the perpendicular bisector of the base is also the angle bisector of the opposite vertex.
