When two parallel lines are crossed by another line the angles in matching corners are called corresponding angles. In the given diagram angles DCF and GFH are corresponding angles.

Corresponding angles in a system of parallel lines crossed by a transversal are congruent (have the same measure)

Then, angle GFH has the same measure than angle DCF:


undefined
