Step-by-step explanation:

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.
