Topic:
Angles
The two quadrilaterals have equal corresponding angles. Are they similar (scaled copies of each other)? Why or why not? Move figure EFGH with point E. Change the shape of ABCD by moving A, B, C, D. Change the shape of EFGH with F and G.
What else would you need to be true about these quadrilaterals to guarantee that they are similar?
