Proving Angles Congruent (2)
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.)
