Learn it A square is a special rectangle and a special rhombus. All rectangles and rhombuses are parallelograms. A trapezoid has exactly one pair of parallel sides. The angles of any quadrilateral add to 360°.

Example: Three angles of a quadrilateral are 90°, 85° and 110°. Find the fourth.

The angles add up to 360°.
$90 + 85 + 110 = 285$.
$360 - 285 = 75$°.
