[size=150][b]What do you think is happening to the triangle here? What did you notice?[/b][/size]
Below you can see our original rotation - triangle DEF rotating 140° counterclockwise around point J. You'll also see line MN (purple) and line KL (orange) with their intersecting point O and the angle between them. Move around the line MN, line KL, and point O and put them in a place where you can reflect the triangle twice (once over each line) and get the same end result as the rotation.[br][br]NOTE: You can move points K, L, M, N individually to get the line/intersection where you want it. You can also select the middle of the line and move the whole thing. Make sure you are using the selection tool to move things.
[size=150][b]What did you need to do to make the second reflection match the original rotation?[/b][/size]
[b][size=100][size=150]Imagine that [/size][/size][/b][b][size=100][size=150]the rotation angle at point J was 100° instead of 140°. [/size][/size][/b][b][size=100][size=150]Describe the lines, angle, and connecting point you would need to be able to reflect twice and match the rotation.[/size][/size][/b]
