RECTANGLES AND RHOMBUSES AND SQUARES, OH MY!

There are three types of parallelograms: rectangles, rhombuses, and squares.

WHAT ARE THE PROPERTIES OF PARALLELOGRAMS?

All parallelograms have two pairs of parallel sides. A rectangle has four right angles, a rhombus has four congruent sides, and a square has four congruent sides and right angles.

Therefore, rectangle + rhombus = square

TRAPEZOID VS ISOSCELES TRAPEZOID

TRAPEZOID

A trapezoid is a quadrilateral with one pair of parallel sides.

ISOSCELES TRAPEZOID

An isosceles trapezoid has congruent legs.
Both trapezoids and isosceles trapezoids have opposite congruent angles
