Which quadrilaterals have

b)opposite angles congruent?

c) two pairs of parallel sides?

d) a pair of congruent, adjacent sides?

My answers

a)rhombus and square

b)rhombus, square, and parallelogram

c)parallelogram, rectangle, and square

d) at first I thought it was a kite, but kite has 2 pairs of congruent adjacent sides so this answer would be a general quadrilateral with 2 sides congruent.

Am I correct or did I forget something?
