Rectangle and Parallelogram Properties

A rectangle is a parallelogram and also has which properties:

• four right angles

• diagonals are congruent

• diagonals form a right angle AKA are perpendicular

• four congruent sides

Which quadrilaterals have two pairs of opposite sides that are parallel?

• rectangle

• rhombus

• parallelogram

• trapezoid

• square

Which quadrilaterals have two pairs of opposite sides that are congruent?

• rectangle

• rhombus

• parallelogram

• trapezoid

• square

Which quadrilaterals have consecutive angles (angles next to eachother) that are supplementary (=180°)?

• rectangle

• rhombus

• parallelogram

• trapezoid

• square

Which quadrilaterals have diagonals that bisect eachother?

• rectangle

• rhombus

• parallelogram

• trapezoid

• square

Which quadrilaterals have diagonals that are congruent?

• rectangle

• rhombus

• parallelogram

• trapezoid

• square

Answer explanation

Diagonals are congruent when there are 4 right angles, and only squares and rectangles have 4 right angles.

Which quadrilaterals have diagonals that are perpendicular?

• rectangle

• rhombus

• parallelogram

• trapezoid

• square

Answer explanation

Diagonals will be perpendicular if the parallelogram has four congruent sides. Only rhombi and squares have four congruent sides.

Which quadrilaterals have diagonals that bisect opposite angles?

• rectangle

• rhombus

• parallelogram

• trapezoid

• square

Answer explanation

Diagonals bisect opposite angles when you have four congruent sides, and square and rhombi have four congruent sides.
