# Proving Angles Congruent

In the applet below, use the provided transformational geometry tools within the limited toolbar

**to prove**that**angle A****IS CONGRUENT TO****angle B**.__Remember:__**Using the Angle tool to simply find display the measures of angle A and angle B****IS NOT how we prove these 2 angles are congruent.**(The fact that congruent angles have equal measures is the**EFFECT**of these angles being congruent,**NOT the CAUSE.**) If you don't recall what it means for angles to be considered congruent, click here for a refresher.Download our apps here:
