[size=85][size=100]In the applet below, given ∆ABC, use the [b]Segment[/b] tool to draw ∆A'B'C' such that A'B' =[br]2AB, A'C'= 2AC, and B'C'= 2BC.[/size][/size]

1.) How did you draw ∆A'B'C'?[br][br]2.) What do you observe about the angles of the two triangles? [br][br]3.) Draw other triangles satisfying the same conditions and see if your observations[br]hold. [br][br][br]

In your lesson on Triangle Congruence, you have learned about corresponding angles and corresponding sides. In the two triangles above, the pairs of corresponding angles are A and A’, B and B’, and C and C’. The pairs of corresponding sides are AB and A’B’, BC and B’C’ and AC and A’C’.
