segments .
Types of QuadrilateralsSquare: Quadrilateral with four equal
sides and four right angles (90 degrees)
Indicates equal sidesBox indicates 900 angle
Types of QuadrilateralsRectangle: Quadrilateral with two pairs
of equal sides and four right angles (90 degrees)
Indicates equal sidesBox indicates 900 angle
Types of QuadrilateralsParallelogram: Quadrilateral with
opposite sides that are parallel and of equal length and opposite
angles are equal
Indicates equal sides
Types of QuadrilateralsRhombus: Parallelogram with four equal
sides and opposite angles equal Indicates equal sides
Types of QuadrilateralsTrapezoid: Quadrilateral with one pair of
parallel sides
