Reflecting a Polygon

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