In this applet you'll explore how rotating a shape affects it.
Click on rotate around a point, then click point D and the triangle provided.
Enter 90 degrees.
What do you notice about the coordinates and size of the rotated triangle?
Rotate it another 90 degrees, and observe the coordinates and size again.
Repeat this several times, then try other shapes and points, and use different angle sizes.
