Quadrilaterals Flashcards
Properties of a parallelogram
Opposite sides R congruent and parallelOpposite angles are congruent Consecutive angles are supplementaryDiagonals bisect each other and divide a parallelogram into 2 congruent triangles
Properties of a Rectangle
6 properties of a parallelogram4 right anglesDiagonals are congruent
Properties of a rhombus
All 6 properties of a parallelogramAll sides are congruent(consecutive sides)Diagonals are perpendicular to each other / and bisect angles
Properties of a Square
Combination of a parallelogram, and rhombus
Properties of a Trapeoid
One pair of opposite sides are parallel(bases)Pair of sides non parallel (legs)
Isosceles Trapezoid
Properties of a trapezoidNon parallel legs are congruentBoth pairs of base angles are congruentDiagonals are congruent
Right trapezoid
One right angle
Any 2 consecutive sides are congruent
Rhombus& square
All angles are congruent
Rectangle & square
Diagonals are perpendicular to each other
Rhombus & square
Diagonals bisect each other
Parallelogram, rectangle, rhombus, & square
