Angle FBC is congruent to angle EDA - given.

BC=AD - The parallel sides of the parallelogram are congruent

Angle BCA is congruent to angle CAD - WHY?

From the above we can conclude that:

triangle FBC congruent to triangle EDA. (ASA)

So, BF=ED (corresponding sides on congruent to triangles). - Aug 9th 2011, 04:00 PMCrayolaRe: Help in proving these two line segments are congruent?
