Question

if the triangle ABC, E is the midpoint of AC and D is the midpoint of CB. If DF is Parallel to BE, Find the length of AB?

Answer 1

Segment DF is parallel to segment EB. D is the midpoint of segment CB.
If a segment passes through the midpoint of one side of a triangle and is parallel to the third side of the triangle, then the segment also passes through the midpoint of the other side of the triangle.
