2D Shapes Definition
In maths, 2d shapes can be defined as the plane figures that can be drawn on a flat (or plane) surface or a piece of paper. All the 2d shapes have various parameters such as area and perimeter. Some of the 2d shapes contain sides and corners, whereas some have curved boundaries.
2D Shapes Names
- Circle
- Triangle
- Square
- Rectangle
- Pentagon
- Octagon
The basic types of 2d shapes are a circle, triangle, square, rectangle, pentagon, quadrilateral, hexagon, octagon, etc. Apart from the circle, all the shapes are considered as polygons, which have sides. A polygon which has all the sides and angles as equal is called a regular polygon. Including the circle, an ellipse is also a non-polygon shape. Both circle and ellipse have a curved shape, whereas the polygons have a closed structure with sides. Now let us discuss some shapes one by one.
Circle
A circle is a closed 2d figure in which the set of all the points in the plane is equidistant from a given point called “center”. The distance from the center to the outer line of the circle is called a radius. The example of the circle in real life are wheels, pizzas, orbit, etc.
