Answer 3

Look at this definition:

Rhombus

A parallelogram with four congruent sides. Note that the diagonals of a rhombus are perpendicular (as is the case with all kites).

Note: A square is a special kind of rhombus.

Answer 4

B. a quadrilateral with four right angles NOT correct

A rhombus has to be equilateral (all sides the same) and there is nothing about option B that suggests that.

A rhombus is a parallelogram because a rhombus has both pairs of opposite sides parallel.
