Reflecting a Polygon
Read the directions and complete the problems below.
Step 1: Create a polygon with the following vertices A(-4, 1), B(-2, 4), C(3, 1), and D(-1, -1) Step 2: Decide which line you are reflecting over. *If you are reflecting across either axis, move to step 4 *If you are reflecting over a line that is NOT an axis, the line must first be graphed. Step 3: Graphing a line a) Click (3rd button). This tool will let you graph using two points. b) Graph a line (in y = mx+b form) c) The line can move by dragging either point. Step 4: Reflecting a) Click (8th button) and choose reflecting about a line. b) Click the polygon. c) Click the line of reflection (axis or the line you've graphed) Note: If you move points A, B, C, or D the corresponding image point will appropriately change as well. Problem #1: R x-axis(ABCD) Problem #2: R y=-1/2x +4(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!!!!
