Now what about the shape over here that has three sides one two three you could also say it has three corners one two three if you have three sides we call that a triangle Tri angle whenever you see this Tri over hear that's a good sign that you're dealing with the number three.
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.
