Dynamic Sketches

Create 2 dynamic sketches to show TH 4-5 and Th 4-7.

A dynamic sketch is a sketch that when you move the figure it stays as desired. Ie if we had a square and you move on corner, all the sides would expand the same amount to retain the square shape.

Your sketch for Th 4-5 will look like below, where a is moveable, but stays on perpendicular bisector. Show me both when you are done.

Now create these dynamic sketches to show:

Th5-1 In a parallelogram, opposite sides are congruent

Th5-2 In a parallelogram, opposite sides are congruent

Th5-3 In a parallelogram, diagonals bisect each other
