Knowing Quadrilaterals

Vocabulary flashcards covering the definitions and geometric properties of special quadrilaterals including parallelograms, rectangles, rhombuses, and squares.

Parallelogram

Rhombus

A special quadrilateral with $4$ equal sides and opposite sides that are parallel. Its diagonals are perpendicular and bisect each other.

Square
