properties, theroems, postulates, definitions, and also all that stuff handling parallelograms, trapezoids, rhombi, rectangles, and also squares... Ns don't recognize why i'm making this haha i hope it helps somebody
| AB | |
| a quadrilateral through both bag of opposite political parties parallel | |
| five properties/theorems for parallelograms | opposite sides space parallel, diagonals bisect every other, opposite sides space congruent, opposite angles are congruent, continually angles are supplementary |
| definition of a rectangle | a square with 4 right angles |
| rectangle theorems | if a parallel is a rectangle, then its diagonals space congruent; if the diagonals of a parallelogram space congruent, climate the paralellogram is a rectangle |
| five nature of a rectangle | opposite sides room congruent and parallel; the opposite angles space congruent; continually angles are supplementary; diagonals are congruent and bisect every other; all four angles are appropriate angles |
| definition the a rhombus | a quadrilateral with four congruent sides |
| rhombus theroems | the diagonals of a rhombus are perpendicular; if the diagonals the a parallelogram are perpendicular, then the paralellogram is a rhombus; every diagonal the a rhombus bisects a pair of opposite angles |
| properties the a rhombus | all parallel properties apply; all 4 sides room congruent; diagonals room perpendicular; the diagonals bisect the opposite angles |
| definition that a square | a quadrilateral with four right angles and four congruent sides |
| properties of a square | the properties of a rectangle to add the properties of a rhombus; four right angles; all 4 sides space congruent |
| definition the a trapezoid | a quadrilateral with precisely one pair that parallel sides |
| definition of an isosceles trapezoid | a trapezoid v the legs congruent |
| isosceles trapezoid theroems | both pairs of basic angles room congruent; the diagonals space congruent |
| trapezoid typical theorem | the average of a trapezoid is parallel come the bases and also its measure is one-half the amount of the steps of the bases, or median=1/2(x+y) |
| in these 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 this quadrilaterals, the diagonals are perpendicular | rhombus, square |
| a rhombus is always a... You are watching: Do diagonals bisect angles in a rectangle | 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 of parallel sides |
| a trapezoid is never a... | parallelogram, rhombus, rectangle, or square, due to the fact that trapezoids only have actually one pair that parallel sides |
| these quadrilaterals constantly have all 4 congruent sides | rhombus, square |
| these quadrilaterals always have all four right angles | rectangle, square |
| these quadrilaterals constantly have perpendicular diagonals | rhombus, square |
| if you division a square into 4 right triangle by drawing its two diagonals, the measure of each of the angles in the triangles that is no a right angle is... | 45 degrees |
| the diagonals that a rhombus... | are not constantly congruent, however they are constantly perpendicular and they do constantly bisect each other, and also they do always bisect the pairs of opposite angles |
| the diagonals that a rectangle... See more: The Three Pigments That Contribute To Skin Color Are, Normal And Abnormal Skin Color | are not constantly perpendicular, but they are constantly congruent and they always bisect each other |
| the diagonals that a parallelogram... | always bisect every other |
