# What is the name for a quadrilateral with all right angles and opposite sides that are parallel and congruent?

Name of Quadrilateral | Description |
---|---|

Rectangle | 2 pairs of parallel sides. 4 right angles (90°). Opposite sides are parallel and congruent. All angles are congruent. |

Square | 4 congruent sides. 4 right angles (90°). Opposite sides are parallel. All angles are congruent. |

Trapezoid | Only one pair of opposite sides is parallel. |

Moreover, which figure is a quadrilateral that has opposite sides that are congruent and parallel?

parallelogram

Also, what is a quadrilateral with one set of parallel sides and two right angles? A square can be defined as a rhombus which is also a rectangle – in other words, a parallelogram with four congruent **sides** and four **right angles**. A trapezoid is a **quadrilateral** with exactly **one pair of parallel sides**.

Subsequently, one may also ask, what quadrilateral always has four congruent angles and opposite sides that are congruent and parallel?

rhombus

What do you call a quadrilateral with no parallel sides?

A trapezium is defined by the properties it **does not** have. It has **no parallel sides**. If the **quadrilateral** had one pair of **parallel sides**, it **would** be a trapezoid. If both pairs of **sides are parallel**, it **would** be a parallelogram.
