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 parallelogram
AB
a quadrilateral v both bag of opposite political parties parallel
five properties/theorems for parallelogramsopposite sides are parallel, diagonals bisect every other, the opposite sides space congruent, the contrary angles are congruent, continually angles space supplementary
definition that a rectanglea quadrilateral with 4 right angles
rectangle theoremsif 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 rectangleopposite 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 rhombusa square with 4 congruent sides
rhombus theroemsthe 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 rhombusall parallel properties apply; all four sides are congruent; diagonals room perpendicular; the diagonals bisect the contrary angles
definition of a squarea square with four right angles and also four congruent sides
properties the a squarethe nature of a rectangle plus the properties of a rhombus; four right angles; all 4 sides space congruent
definition that a trapezoida quadrilateral with specifically one pair the parallel sides
definition of an isosceles trapezoida trapezoid through the legs congruent
isosceles trapezoid theroemsboth pairs of basic angles room congruent; the diagonals are congruent
trapezoid typical theoremthe 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 otherparalellogram, rectangle, rhombus, square
in this quadrilaterals, the diagonals are congruentrectangle, square, isosceles trapezoid
in these quadrilaterals, each of the diagonals bisects a pair of opposite anglesrhombus, square
in these quadrilaterals, the diagonals room perpendicularrhombus, square
a rhombus is always a...

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 sidesrhombus, square
these quadrilaterals always have all 4 right anglesrectangle, square
these quadrilaterals always have perpendicular diagonalsrhombus, 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...

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
