#63.)in the window bd ~= df~=hf. also need aswell with part a and b to the problem. attached a picture file below for a better understanding. a.) b.)

A) HBDF is a rhombus; ACEG is a rectangle

B) The diagonals are congruent; the listed half-diagonals are congruent

Step-by-step explanation:

A) A quadrilateral (HBDF) with equal length sides (given) is a rhombus (by definition).

A quadrilateral (ACEG) with right-angle corners is a rectangle (by definition).

___

B) The diagonals AE and GC are those of a rectangle, so are congruent and bisect each other. Hence, the pieces are all congruent.
