Rotating a Polygon
Read the directions and complete the problems below.
Step 1: Create a polygon with the following vertices    
      A(-1, 2), B(1, 3), C(2, 5), and D(-2, 4) 
Step 2: Decide which point you are rotating around. Use the point tool 
 (2nd button) to plot a point.  Note: The point created needs to be bright blue.  If you get a black dot or a light blue dot, delete it.  Create a dot someplace else and move it to where you need it to be. 
Step 3: Rotating 
      a) Click 
 (8th button) and choose rotating about a point 
      b) Click the polygon. 
      c) Click the center of rotation
      d) Enter the angle of rotation.  All angles will be entered a positive. Click          counterclockwise or clockwise for the direction. 
Note: If you move points A, B, C, or D the corresponding image point will appropriately change as well.  
Problem #1: r(90, O )(ABCD)       
Problem #2: r(-90, (5, 1)) (ABCD)
*Perform each transformation within this applet.  
**Take a screen shot of your work (you will have problem #1 and problem #2 on one screenshot.)  Insert it into the appropriate google slide.
