a. Lin is using the diagram to prove the statement, "If a parallelogram has one
right angle, it is a rectangle." Given that EFGH is a parallelogram and angle
HEF is a right angle, write a statement that will help prove angle FGH is also
a right angle.
b. Han then states that the 2 triangles created by diagonal BG must be congruent.
Help Han write a proof that triangle EHG is congruent to triangle GFE.
