2.)You are trying to find the distance AB between two points on either side of a river. You
measure the following distance:
E
D
ED = 32 ft
EC = 32 ft
DC = 28 ft
AC = 28 ft
BC = 32 ft
If you rotate Triangle ECD 180 degrees clockwise, you will see that the sides line up perfectly with Triangle BCA, meaning that ED = AB and ED = 32 (transitive property of equality) so AB must also equal 32.
