2D & 3D SHAPES

 

2D AND 3D SHAPES

SHAPES: 

The shape can be defined as the boundary or outline of an object. In general, we can see shapes such as triangles, squares, and circles everywhere around us. Thus shapes have only lenght and breadth are 2D or two-dimensional. while other shapes such as the shape of a house have length, breadth and height. Thus shapes are 3D or three-dimensional.

2D SHAPES: 

                         A 2D shapes has two dimensions lenght and breadth.

examples: Rectangle, Square, Circle, Triangle.

3D SHAPES:

                       A 2D shapes has three dimensions lenght, breadth and height.

examples: Cuboid, Cube, Cylinder, Sphere.

See the above image the 1st one is circle and it is in 2D shape and the 2nd one is sphere and it is in 3D shape.

Here are some 2d and 3d shapes

Differences between 2D and 3D shapes

You (or the children in your class) might be wondering about the differences between 2D and 3D shapes. This is a really good question, since it can be confusing to understand what dimensions are and what they mean.

If an object has three dimensions, there are 3 ways it can be measured in space. You can measure the length, breadth and height of 3D objects.

So, unlike 2D shapes, 3D shapes aren't flat – they have depth. 

But the most important thing for children to remember is that the main difference between shapes in 2D and 3D is their dimensions. 2D shapes have two dimensions and 3D shapes – yes, you guessed it, they have 3 dimensions.
