Aimee and Sam are building a bookshelf with a trapezoid as the base shape. Each shape has its different properties based on the sides, length, area, angle etc. All the shapes are polygons except circles. We come across 2D Shapes in our day-to-day life in the form of circles, triangles, squares, rectangles and pentagons. True or False: All squares are rhombuses, but not all rhombuses are squares. Two-dimensional shapes are defined as plane figures consisting of length and breadth. A two-dimensional shape is a flat plane shape that has two dimensions: length and breadth (or width).

A quadrilateral is a sided two-dimensional shape. For example, if you need two figures, such as (2, 4), to understand where a particular spot is, you are dealing with a two-dimensional shape. Here are a few sample questions going over quadrilaterals. Regular Polygons A polygon is a 2D shape with straight sides. Trending Questions What 2d shape has four equal sides but no right angles? What is the volume of a cylinder with diamter of 6cm and height of 5cm? What is an example of an undecagon? What is the solution of Two sides of a rectangle differ by 3. A dimension in geometry is defined as the number of coordinates needed to specify a point on the object, according to Wolfram MathWorld. 2D Shapes - Polygons and More 2D Shapes A plane or 2D shape has 2 Dimensions (such as width and height) but no thickness.
