Task 3 - Connecting Vertices of Similar Triangles

Shown in the applet below are ∆EFG and ∆RST.
Questions
1.)    Are the two triangles similar? Why?[br][br]2.) Use the Line tool to connect the corresponding vertices of the two triangles. What do you observe about the lines?[br][br]3.)  Draw another triangle that is similar to ∆EFG and name it ∆HJI. Connect their corresponding vertices. Did your observation in 2 also hold?
