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

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

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
