properties, theroems, postulates, definitions, and all the stuff managing parallelograms, trapezoids, rhombi, rectangles, and also squares... Ns don't understand why i'm do this haha ns hope it helps somebody
| AB | |
| a quadrilateral through both bag of opposite political parties parallel | |
| five properties/theorems for parallelograms | opposite sides are parallel, diagonals bisect every other, the opposite sides are congruent, opposite angles space congruent, continually angles room supplementary |
| definition that a rectangle | a square with four right angles |
| rectangle theorems | if a parallelogram is a rectangle, then its diagonals are congruent; if the diagonals that a parallelogram space congruent, climate the paralellogram is a rectangle |
| five nature of a rectangle | opposite sides room congruent and parallel; opposite angles room congruent; continually angles room supplementary; diagonals are congruent and bisect each other; all four angles are ideal angles |
| definition that a rhombus | a square with four congruent sides |
| rhombus theroems | the diagonals of a rhombus room perpendicular; if the diagonals that a parallelogram are perpendicular, then the paralellogram is a rhombus; every diagonal the a rhombus bisects a pair of the opposite angles |
| properties of a rhombus | all parallel properties apply; all four sides room congruent; diagonals are perpendicular; the diagonals bisect opposite angles |
| definition the a square | a square with four right angles and four congruent sides |
| properties of a square | the nature of a rectangle to add the nature of a rhombus; four right angles; all 4 sides space congruent |
| definition that a trapezoid | a square with exactly one pair the parallel sides |
| definition of an isosceles trapezoid | a trapezoid through the legs congruent |
| isosceles trapezoid theroems | both bag of base angles room congruent; the diagonals space congruent |
| trapezoid average theorem | the typical of a trapezoid is parallel come the bases and 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 each other | paralellogram, rectangle, rhombus, square |
| in these quadrilaterals, the diagonals room congruent | rectangle, square, isosceles trapezoid |
| in this quadrilaterals, each of the diagonals bisects a pair of the contrary angles | rhombus, square |
| in this quadrilaterals, the diagonals room perpendicular | rhombus, square |
| a rhombus is always a... You are watching: In which quadrilateral are the diagonals always congruent | parallelogram |
| a square is always a... | parallelogram, rhombus, and rectangle |
| a rectangle is always a... | parallelogram |
| a square is never a... | trapezoid, since trapezoids only have actually one pair of parallel sides |
| a trapezoid is never a... | parallelogram, rhombus, rectangle, or square, because trapezoids only have actually one pair that parallel sides |
| these quadrilaterals constantly have all 4 congruent sides | rhombus, square |
| these quadrilaterals constantly have all 4 right angles | rectangle, square |
| these quadrilaterals always have perpendicular diagonals | rhombus, square |
| if you division a square into 4 right triangle by illustration its 2 diagonals, the measure of each of the angle in the triangles that is no a appropriate angle is... | 45 degrees |
| the diagonals that a rhombus... | are not always congruent, however they are constantly perpendicular and they do constantly bisect each other, and also they do always bisect the pairs of the opposite angles |
| the diagonals that a rectangle... See more: What Is The Answer To A Subtraction Problem Is Called ? Terms Of The Subtraction | are not always perpendicular, yet they are constantly congruent and also they always bisect each other |
| the diagonals the a parallelogram... | always bisect each other |
