Rotating a Polygon

Read the directions and complete the problems below.
Step 1: Create a polygon with the following vertices  [br]  A(-1, 2), B(1, 3), C(2, 5), and D(-2, 4) [br][br]Step 2: Decide which point you are rotating around. Use the point tool [icon]/images/ggb/toolbar/mode_point.png[/icon] (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. [br][br]Step 3: Rotating [br]  a) Click [icon]https://tube.geogebra.org/images/ggb/toolbar/mode_mirroratline.png[/icon] (8th button) and choose rotating about a point [icon]/images/ggb/toolbar/mode_rotatebyangle.png[/icon][br]  b) Click the polygon. [br]  c) Click the center of rotation[br]  d) Enter the angle of rotation.  All angles will be entered a positive. Click   counterclockwise or clockwise for the direction. [br][br]Note: If you move points A, B, C, or D the corresponding image point will appropriately change as well.  [br][br][b]Problem #1: r(90, O )(ABCD) [/b]  [br][br][b]Problem #2: r(-90, (5, 1)) (ABCD)[br][br][/b][b]*Perform each transformation within this applet.  [br][br][/b]**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.  [br]***Geogebra will NOT save your work!!!!
