Let's examine what happens when a figure is reflected twice across intersecting lines!
1. Pivot both lines of reflection and become familiar with how the figures move around when the lines are moved. Also, try reshaping the original figure by sliding the points around.
2. How does the angle that the new figure (double prime) has rotated compare to the angle formed by the 2 lines of reflection?
