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.
