2D and 3D shapes

Front

What is a 2D shape?

Back

A 2D shape, or two-dimensional shape, is a flat figure that has only length and width, but no depth. Examples include squares, circles, and triangles.

Front

What is a 3D shape?

Back

A 3D shape, or three-dimensional shape, has length, width, and depth. Examples include cubes, spheres, and pyramids.

Front

Name three examples of 2D shapes.

Back

Circle, square, triangle.

Front

Name three examples of 3D shapes.

Back

Cube, sphere, cylinder.

Front

What is the difference between 2D and 3D shapes?

Back

The main difference is that 2D shapes have only two dimensions (length and width), while 3D shapes have three dimensions (length, width, and depth).

Front

How can you identify a 2D shape?

Back

A 2D shape can be identified by its flatness and the absence of depth. It can be drawn on a flat surface.

Front

How can you identify a 3D shape?

Back

A 3D shape can be identified by its volume and the presence of depth. It occupies space and can be held.

Front

What is the perimeter of a 2D shape?

Back

The perimeter is the total distance around the outside of a 2D shape, calculated by adding the lengths of all its sides.

Front

What is the surface area of a 3D shape?

Back

The surface area is the total area that the surface of a 3D shape occupies, calculated by summing the areas of all its faces.

Front

What is the volume of a 3D shape?

Back

The volume is the amount of space a 3D shape occupies, measured in cubic units.
