One two three four sides as long as as four sides it's a quadrilateral Let's think about each of these so this shape right over here what you might see is the corners the corners all come in, sometimes is called square sometimes you could call it a right angle so and notice I could put little small squares here.
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.
