The Properties of 2D and 3D

Shapes

PART 1

SOLID SHAPES

Three-dimensional Shapes (3D)

These shapes are solid

or hollow.

They have three

dimensions length, width and height. Face

Part of a shape that is

flat.(Or curved)

E.g. A cube has 6

of these. Edge

The line where two

faces meet.

E.g. A cube has 12 of

these.

Vertex (Vertices)

The place where three

or more edges meet.

This pyramid has 4 of

these.

Parallel

These type of lines

stay the same distance apart for their whole length. They do not need to be straight or the same length. Cube

A 3D shape.

6 square faces all the

same size.

12 Edges all the same

length.

8 Vertices.

square.

Cuboid

A 3D shape.

6 rectangular faces.

12 Edges.

8 Vertices.

rectangle.

Sphere

A perfectly round 3D

shape, like a ball.

It has only one curved

face. circle. Cone

A 3D shape.

Has a circle at its base

and a pointed vertex.

Has 2 faces.

Cylinder

A 3D shape.

Circular ends of equal

size.

2 Edges.

3 Faces.

0 Vertices.

Square base pyramid

A 3D shape.

Has a square base-

Face 1.

4 triangular faces.

5 faces in total.

8 Edges.

5 Vertices.

PART 2

PLANE SHAPES

Two-dimensional Shapes (2D)

These shapes are flat

and can only be drawn on paper.

They have two

dimensions length and width.

They are sometimes

called plane shapes.

Polygons

Two-dimensional shapes

that have sides made from straight lines.

E.g. triangles

squares hexagons

Quadrilaterals

Any 2D shapes with

four straight sides.

E.g. square

rhombus rectangle trapezium kite

Circle

A round flat 2D shape.

No Straight sides, only

one curved side.

No corners.

Infinitive lines of

symmetry.

Triangle

A 2D Shape.

3 straight sides.

3 Corners.

A regular triangle

(equilateral) has 3 lines of symmetry.

Can you name 4

different kinds?

Square

A 2D shape.

4 sides of the same

length.

4, 90 angles.

4 corners.

4 Lines of symmetry.

Rectangle

A 2D shape.

four straight sides

Has two pairs of

parallel sides that meet at right angles.

This means 2 sides are

long and 2 are shorter.

2 Lines of symmetry.

Pentagon

A 2D shape.

5 straight sides.

5 Corners.

5 Lines of Symmetry.

Hexagon

A 2D shape.

6 straight sides

6 Corners.

6 Lines of symmetry.

Octagon

A 2D shape.

8 straight sides

8 Corners.

8 Lines of Symmetry.
