This figure has two parallel sides.

It also has 2 pairs of adjacent angles which are supplementary.

It is a trapezoid.

"isoscelesTrapezoid"
Isosceles Trapezoid

This figure has two parallel sides.

It also has 2 pairs of adjacent angles which are supplementary.

It is a trapezoid.

However, its legs are equal, so it is an isosceles trapezoid.

"parallelogram"
Parallelogram

Opposite angles of this quadrilateral are equal.

Adjacent angles are supplementary.

It has 2 pairs of parallel sides.

Parallel sides are equal.

Therefore it is a parallelogram.

"rectangle"
Rectangle

This quadrilateral has 2 pairs of parallel sides.

Its angles are equal to 90.

Therefore it is a rectangle.

Square

This quadrilateral has 2 pairs of parallel sides.

Its angles are equal to 90.

All sides are equal.

Therefore it is a square.

"kite"
Kite

This quadrilateral has two pairs of equal sides.

Those sides are adjacent.

It also has a pair of equal angles, positioned between the non-equal sides.

It is a kite.

"rhombus"
Rhombus

This quadrilateral has all sides equal.

Therefore it is a rhombus.
