Directions

Create a Triangle using your Polygon tool, on top of Triangle A. Then create two lines using your Line tool that duplicate the lines given in the picture. Place a point at R on the two intersecting lines you just created. Try and rotate your triangle around R so that it maps onto triangle B. After you have successfully rotated your triangle onto triangle B, reflect A over the lines your created to map your triangle onto Triangle B. Can you rotate and reflect triangle A to create triangle B?
