The shapes of elementary geometry are invariably convex. Starting with the most regular quadrilateral, namely, the square, we shall define other shapes by relaxing its properties. A square is a quadrilateral with all sides equal and all angles also equal. Angles in any quadrilateral add up to 360Â°. It follows that, in a square, all angles measure 90Â°. An equiangular quadrilateral, i.e. the one with all angles equal is a rectangle. All angles of a rectangle equal 90Â°. An equilateral quadrilateral, i.e. the one with all sides equal, is a rhombus. In a square, rectangle, or rhombus, the opposite side lines are parallel.
