Question

prove that the bisector of the vertical image of an isosceles triangle bisects the base ​

Answer 1

There is a theorem which says that if two angles, a and b, are equal, then they have two opposite sides, r and t, respectively, which are also equal. ... Then if AB = AC we can confirm that this bisects the base at the middle point of BC, and makes a right angle.
