properties, theroems, postulates, definitions, and also all the stuff managing parallelograms, trapezoids, rhombi, rectangles, and also squares... Ns don't understand why i'm making this haha ns hope it helps somebody

definition of a parallelogramAB | |

a quadrilateral v both bag of opposite political parties parallel | |

five properties/theorems for parallelograms | opposite sides are parallel, diagonals bisect every other, the opposite sides space congruent, the contrary angles are congruent, continually angles space supplementary |

definition that a rectangle | a quadrilateral with 4 right angles |

rectangle theorems | if a parallel is a rectangle, then its diagonals are congruent; if the diagonals that a parallelogram space congruent, then the paralellogram is a rectangle |

five properties of a rectangle | opposite sides space congruent and also parallel; opposite angles room congruent; consecutive angles room supplementary; diagonals space congruent and bisect each other; all four angles are best angles |

definition the a rhombus | a square with 4 congruent sides |

rhombus theroems | the diagonals the a rhombus room perpendicular; if the diagonals the a parallelogram space perpendicular, then the paralellogram is a rhombus; every diagonal that a rhombus bisects a pair of opposite angles |

properties of a rhombus | all parallel properties apply; all four sides are congruent; diagonals room perpendicular; the diagonals bisect the contrary angles |

definition of a square | a square with four right angles and also four congruent sides |

properties the a square | the nature of a rectangle plus the properties of a rhombus; four right angles; all 4 sides space congruent |

definition that a trapezoid | a quadrilateral with specifically one pair the parallel sides |

definition of an isosceles trapezoid | a trapezoid through the legs congruent |

isosceles trapezoid theroems | both pairs of basic angles room congruent; the diagonals are congruent |

trapezoid typical theorem | the mean of a trapezoid is parallel to the bases and also its measure is one-half the amount of the actions of the bases, or median=1/2(x+y) |

in this quadrilaterals, the diagonals bisect every other | paralellogram, rectangle, rhombus, square |

in this quadrilaterals, the diagonals are congruent | rectangle, square, isosceles trapezoid |

in these quadrilaterals, each of the diagonals bisects a pair of opposite angles | rhombus, square |

in these quadrilaterals, the diagonals room perpendicular | rhombus, square |

a rhombus is always a... You are watching: Does a rectangle have perpendicular diagonals | parallelogram |

a square is constantly a... | parallelogram, rhombus, and rectangle |

a rectangle is always a... | parallelogram |

a square is never ever a... | trapezoid, due to the fact that trapezoids only have actually one pair the parallel sides |

a trapezoid is never ever a... | parallelogram, rhombus, rectangle, or square, since trapezoids only have one pair of parallel sides |

these quadrilaterals constantly have all four congruent sides | rhombus, square |

these quadrilaterals always have all 4 right angles | rectangle, square |

these quadrilaterals always have perpendicular diagonals | rhombus, square |

if you division a square into four right triangles by illustration its two diagonals, the measure of every of the angle in the triangles that is no a right angle is... | 45 degrees |

the diagonals of a rhombus... | are not always congruent, however they are constantly perpendicular and also they do always bisect every other, and they do constantly bisect the pairs of the opposite angles |

the diagonals of a rectangle... See more: How Many Cups Is 50 Ounces To Cups, How Many Cups | are not always perpendicular, yet they are constantly congruent and also they always bisect every other |

the diagonals that a parallelogram... | always bisect each other |
