Quadrilaterals And Parallelogram
Quadrilaterals are four-sided plane figures.(A polygon
with four sides).
Special Types of Quadrilaterals:
A parallelogram is a quadrilateral in which both pairs of opposite
sides are parallel.
A parallelogram is a quadrilateral in which both
pairs of opposite sides are parallel.
A square: parallelogram with four
congruent sides and four right angles.

Squares Quadrilaterals and parallelograms
A rectangle is a parallelogram with four right
angles, so all rectangles are also
parallelograms and quadrilaterals.

Rectangles Quadrilaterals and parallelograms
A trapezoid is a quadrilateral with exactly one pair of parallel
sides.
A kite is a quadrilateral with exactly two pairs of adjacent
congruent sides.
A rhombus is a four-sided shape where all sides have
equal length.

In this figure all sids are 60 degrees
