Properties of Rhombuses, Rectangles and Squares

A rhombus is a quadrilateral with all four sides of equal length.

A rectangle is a quadrilateral with opposite sides that are equal and all angles that are right angles (90 degrees).

A square is a quadrilateral that is both a rectangle and a rhombus, meaning all sides are equal and all angles are right angles.

Never true. While all squares are rectangles and rhombuses, not all rectangles are rhombuses.

Consecutive angles of a rectangle are not complementary; they are all right angles.

The diagonals of a rhombus bisect each other at right angles but are not necessarily congruent.

$$4x - 7 = 3x - 10$$ , because all sides of a rhombus are congruent.

The measure of angle 1 is 72 degrees.

Always true. The diagonals of a rectangle are always congruent.

The sum of the interior angles of a quadrilateral is 360 degrees.
