Properties of 2D shapes

2D Shapes

A 2D (two-dimensional) shape is a flat shape that has only two dimensions. 

2D shapes have sides and vertices. A vertex is a point where two or more lines meet. The plural of vertex is vertices.

Properties of a shape are the number of sides and vertices of a shape.

 

Let’s learn about the properties of different 2-D shapes.


Triangle
 

 

 

A triangle has 3 sides and 3 vertices.


 

Square
 

 


 

A square has 4 sides and 4 vertices.


 

Rectangle
 

 

 

A rectangle has 4 sides and 4 vertices.

 

Pentagon
 


 


 

Hexagon

 

A hexagon has 6 sides and 6 vertices.
