Math activity 3 (Q1,Q3 and Q4)

Question 1:
A square is a quadrilateral where all 4 sides are equal, opposite sides are parallel and every meeting point of 2 lines are 90 degrees.
A rhombus is a quadrilateral where all 4 sides are equal, opposite sides are parallel and meeting points of 2 lines can be of any degree.
So a square is a rhombus as all 4 sides are equal and opposite sides are parallel while a rhombus is not a square as a Rhombus might not have 90 degrees.

Question 3:

It would be a trapezium, 
a trapezium would have a 1 pair of opposite line with different length and the other of the same length while diagonally opposite angles would add up to 180 degrees.
Question 4:
No, all squares have right angles while only some parallelogram have right angles.
