In the applet below, use the provided transformational geometry tools within the limited toolbar [b]to prove [/b]that [color=#ff00ff][b]angle A [/b][/color][b]IS CONGRUENT TO [/b][color=#444444][b]angle B[/b][/color]. [br][br][color=#ff0000][b][u]Remember:[/u] [br][/b][/color][b]Using the Angle tool to find the measures of angle A and angle B[/b][color=#ff0000] [b]IS NOT how we prove these 2 angles are congruent.[/b] [/color](The fact that congruent angles have equal measures is the [color=#ff0000][b]EFFECT[/b][/color] of these angles being congruent, [color=#ff0000][b]NOT the CAUSE.[/b][/color]) [br][br]If you don't recall what it means for angles to be considered congruent, [url=https://www.geogebra.org/m/evXSUG9J]click here[/url] for a refresher.
