1. The correct answer is 16 inches. Since the same triangle was rotated multiple times, its sides still have the same measurements. Since AB is 16 inches and it is the hypotenuse, and BG is also the hypotenuse, it is also 16 inches long.
2. The correct answer is 6 inches. Since AD is 3 inches, and BC and FB are congruent to AD, and add up to make FC, FC is 6 inches. In other words, AD, BC, and FB are all 3 inches and FB + BC = FC, so FC = 3 + 3, or 6.
Hope this helps!
