Understanding Medians in Isosceles Triangles

What is the main goal of the proof discussed in the video?

• To prove that all triangles are isosceles

• To prove that medians drawn to the legs of an isosceles triangle are congruent

• To prove that the angles in a triangle sum to 180 degrees

• To prove that the base angles of an isosceles triangle are equal

What is the significance of the medians YA and ZB in the proof?
