Aline m is perpendicular to an angle bisector of a. the sides of a intersect this line m at points m and n. prove that amn is isosceles.

well first you can draw a picture. so draw a line called line m and then draw a line q that is the angle bisector. so you currently have a perpendicular angle. now just draw the angle that makes q the bisector. since angle a is bisected, we can say each half is x amount of degrees. line q is the common side and each line in angle a is the same length, we can use sas equality and call the triangles maq and naq equal. since they both are congruent, we can combine then and say they are isosceles.

man its nopq i just guessed and got it right so uhh
