A 2D shape or two-dimensional shape is a flat figure that has two dimensions—length and width. Learn examples, formulas, properties of 2D shapes and much more!
It consists of a length and a width but does not have any depth or height. Some common 2D shapes are squares, rectangles, triangles, circles, and hexagons. Let us learn more about 2D geometric shapes, the difference between 2D and 3D shapes, along with some 2D shapes examples on this page.
2D shapes are plane shapes that only have the two dimensions of length and width. Polygons are a type of 2D figure that come in an infinite variety of shapes. The area of 2D shapes is measured in squared units, while the perimeter is measured in linear units.
In mathematics—namely geometry—and in real life, geometric shapes are two or three-dimensional figures that can be recognized and categorized based on a specific outline/boundary and other attributes including curves, lines, and angles.
In this unit, you will classify triangles and quadrilaterals, based on the attributes of their sides and angles. You will also learn about lines of symmetry in two-dimensional figures. You will then use these attributes of figures to solve geometric problems, including those about perimeter and area.
Identify basic 2D shapes: rectangles, squares, trapezoids, triangles, etc. Identify basic 3D shapes: cubes, right circular cones, right circular cylinders, etc. Create a shape when given a list of defining attributes.
A 2D shape is a flat shape with sides, vertices and sometimes lines of symmetry. If the sides and vertices on a shape are all the same, the shape is regular. A square is a type of rectangle....
