Answer 3

A and D

Answer 5

Answer 6

C i think

no

Answer 9

A - The congruent sides on the square could be like a rhombus side.

B - A square needs 4 right angle sides (90degrees).

C - A parallelogram isn't really counted as a square because it's sorta like a rectangle and the sides aren't 90 degrees or even in length/height/width.

D - A rhombus is always a rhombus. A square is always a square. A rhombus may have 90 degree angles, but it's not going to define a square. Otherwise, if a rhombus was shaped like a square, then why would we be calling it a rhombus if we could call it a square?
