Question

a) reactangle
b) square
c) parallelogram
d) trapezoid

Answer 1

parallelogram
because it could be a square or rectangle but not a trapezoid because the sides are not congruent

Answer 2

c) parallelogram.

It can't be a trapezoid, because one pair will not be congruent. It may be a rectangle or square, but it doesn't have to be to achieve congruence of both pairs.

Answer 3

c) parallelogram
(Parallelogram: both pairs of opposite sides are parallel. This implies that opposite sides have equal length, opposite angles are equal, and the diagonals bisect each other. )
