Different Types of 2-D Shapes
One way to describe 2-D shapes is by determining whether they are a polygon or non-polygon.
Polygons are made completely out of straight lines.
Non-polygons have curved lines or are not completely closed.
We can also describe 2-D shapes by the number of sides that they have.
A 3-sided shape is called a triangle.
A 4-sided shape is called a quadrilateral. Quad usually means “4”.
