What does 2d shapes look like?

2D shapes can be summarized by calling them flat shapes. Any shape that can be laid flat on a piece of paper or any mathematical plane is a 2D shape. As a child, your first drawings probably used basic shapes, such as squares, triangles, and circles. … Examples of 2D shapes include rectangles, octagons, and even hearts.

What is a 1000000000 sided shape called?

megagonA megagon or 1 000 000-gon is a polygon with 1 million sides (mega-, from the Greek μέγας megas, meaning “great”). Even if drawn at the size of the Earth, a regular megagon would be very difficult to distinguish from a circle.
