### What are the similarities and differences of the 6 quadrilaterals?

All quadrilaterals have four sides. All have interior angles
totalling 360 degrees.
A scalene quadrilateral has no parallel sides.
A trapezoid has one pair of parallel sides and one pair of
non-parallel sides.
A parallelogram has two pairs of parallel sides. Opposite angles
are equal.
A rectangle is a parallelogram with four right angles at the
corners, and therefore all angles are equal.
A rhombus is a parallelogram with all four sides equal.
A square is a rhombus with four right angles, and therefore all
four sides are equal and all four angles are equal.
A square is also a parallelogram with four equal sides.

###### Asked in Geometry

### Why is a trapezoid not a rectangle?

A rectangle has four right angles, two parallel pairs of line
segments, and the lines are perpendicular. A trapezoid has one pair
of parallel angles, and the angles do not have to be right,
although a trapezoid with a right angle is called a right angle
trapezoid, and a trapezoid with no parallel segments is a
trapezium.
