• Pentagon

Select all the properties of parallelograms:

• opposite sides are parallel

• opposite sides are congruent

• opposite angles are congruent

• consecutive angles are supplementary

• diagonals bisect eachother

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 four congruent sides?

• 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 consecutive angles (angles next to eachother) that are supplementary (=180°)?

• rectangle

• rhombus

• parallelogram

• trapezoid

• square

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.
