Properties of Rhombuses, Rectangles and Squares

Front

What is a square?

Back

A square is a quadrilateral with all four sides congruent and all four angles measuring 90 degrees.

Front

What is a rectangle?

Back

A rectangle is a quadrilateral with opposite sides that are congruent and all four angles measuring 90 degrees.

Front

What is a rhombus?

Back

A rhombus is a quadrilateral with all four sides congruent, but the angles are not necessarily 90 degrees.

Front

Are all squares rhombuses?

Back

Yes, all squares are rhombuses because they have all sides congruent.

Front

Are all rhombuses squares?

Back

No, not all rhombuses are squares because rhombuses do not require all angles to be 90 degrees.

Front

What is the relationship between rectangles and parallelograms?

Back

A rectangle is always a parallelogram because it has opposite sides that are congruent and parallel.

Front

What is the relationship between squares and rectangles?

Back

A square is a special type of rectangle where all sides are equal.

Front

What is the formula for the area of a square?

Back

Area = side² (where 'side' is the length of one side of the square).

Front

What is the formula for the area of a rectangle?

Back

Area = length × width.

Front

What is the formula for the area of a rhombus?

Back

Area = (diagonal1 × diagonal2) / 2.
