Complete the proof below. Thank you!!!
![Recall:
An isosceles triangle is a triangle with (at least) two equal sides. This property is equivalent to two angles of
the triangle being equal. An isosceles triangle therefore has both two equal sides and two equal angles.
And
In geometry, a median of a triangle is a line segment joining a vertex to the midpoint of the opposing side, bisecting it.
If triangle ABC is isosceles, with AB = AC, then the medians drawn from vertice B to point M and the median drawn
from vertice C to point N must have the same length. Write a two-column proof to prove this statement given what you
know about isosceles triangles and medians of a triangle.
