Parallelogram: A quadrilateral with both pairs of opposite sides parallel and both pairs an equal length. Kite: A quadrilateral with two pairs of sides that are same length. One pair of diagonally opposite sides is equal. Polygon: A polygon is a 2D shape with straight sides. ...
Properties of an Oval Shape It has no edges. It has no vertices. It is a 2D curved geometrical figure. It has only one flat face. It is a simple curve. It means that it does not overlap or self-intersect. It is convex. It means its surface is curved or rounded outward. ...
2D Shapes In geometry, the term 2D (two-dimensional) refers to a flat plane figure or shape with only two dimensions – length and width, without depth or thickness. An example is a piece of paper, which has a two-dimensional shape. The object here consists of a length and width but ...
