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. ***Geogebra will NOT save your work!!!!
