1.

Task 1

Check out this triangle below. Move the vertices (LARGE POINTS) of this triangle around. As you do, note the length of the bold side doesn't change.
Use the ANGLE [icon]/images/ggb/toolbar/mode_angle.png[/icon] tool to measure the angles of this triangle now. To do this the easy way, select the ANGLE tool [icon]/images/ggb/toolbar/mode_angle.png[/icon], click inside the triangle, and then select the MOVE tool [icon]/images/ggb/toolbar/mode_move.png[/icon] again (to turn the angle tool off). [br][br]Move the vertices (corners) of the triangle around again. Notice anything interesting?
