# Quadrilaterals

### Properties of Quadrilaterals

Quadrilateral | Properties |
---|---|

Polygon | A closed figure with all sides composed of line segments. |

Quadrilateral | Four sided polygon Sum of interior angles is 360 degrees |

Kite | Exactly two distinct pairs of adjacent, congruent sides. Diagonals are perpendicular. One diagonal divides the quadrilateral into two congruent triangles. The other diagonal divides the quadrilateral into two isosceles triangles. |

Trapezoid | Exactly one pair of parallel sides. |

Isosceles Trapezoid | One pair of parallel sides called bases. One pair of congruent sides called legs. Each pair of base angles is congruent. Diagonals are congruent. |

Parallelogram | Opposite sides are parallel. Opposite sides are congruent. Opposite angles are congruent. Consecutive angles are supplementary. Diagonals bisect each other. Each diagonal divides the quadrilateral into two congruent triangles. |

Rectangle | Opposite sides are congruent. Opposite sides are parallel. All angles are right. All diagonals are congruent. |

Rhombus | All sides are congruent Diagonals are perpendicular. Diagonals bisect opposite angles. |

Square | All sides are congruent. Opposite sides are parallel. All angles are right. Diagonals are congruent. Diagonals are perpendicular. diagonals bisect opposite angles. |
