(quiz starts below)

Fascinating Fact:

Irregular polygons have sides and angles of different lengths, often seen in nature or art.

In KS3 Maths, “Names of Shapes” introduces common 2D polygons and their features. You will classify triangles and quadrilaterals, use correct shape vocabulary, describe symmetry, and link names to real examples.

Key Terms

Polygon: A flat, closed shape made from straight line segments.
Regular polygon: A polygon with all sides equal and all angles equal.
Quadrilateral: Any four sided polygon, such as a square, rectangle, kite, or trapezium.

Frequently Asked Questions (Click to see answers)

What is a polygon in KS3 maths?

A polygon is a 2D shape made of straight sides joined end to end to form a closed figure, for example triangles, quadrilaterals, pentagons, and hexagons.

How can I tell a regular polygon from an irregular polygon?

A regular polygon has all sides and all angles equal. If any sides or angles differ, it is an irregular polygon.

What are the names of four sided shapes?

Four sided shapes are quadrilaterals. Common types include square, rectangle, rhombus, parallelogram, kite, and trapezium (a trapezoid in some countries).

Maths Quiz - Level 3-4 Shapes - Names of Shapes (Answers)

1.

Which of the following is one-dimensional?

[ ]	A circle
[ ]	A sphere
[x]	A straight line
[ ]	A triangle

A straight line only has length

2.

A two-dimensional shape has something that a one-dimensional straight line does not have. What is it?

[x]	Area
[ ]	Charisma
[ ]	Symmetry
[ ]	Volume

To work out the area you limes length x width. A one-dimensional straight line has no width and so no area

3.

A two-dimensional shape with straight sides is called a what?

[ ]	Polyester
[x]	Polygon
[ ]	Polygraph
[ ]	Polymath

The word comes from the Greek words for 'many' and 'angles' (but today we think more in terms of 'many' and 'sides')

4.

What is defined as 'a polygon with three corners or vertices and three sides or edges'?

[ ]	Pyramid
[ ]	Quadrilateral
[ ]	Trapezium
[x]	Triangle

A 3-sided shape is of course a triangle

5.

A square, a rectangle, a parallelogram, a rhombus, a kite and a trapezium are all examples of what?

[ ]	Quadratic formula
[ ]	Quadriceps
[x]	Quadrilaterals
[ ]	Quadrophenia

A quadrilateral is a polygon with four corners or vertices and four sides or edges. A quadrilateral is sometimes known as a tetragon for consistency with pentagon (5-sided), hexagon (6-sided) and so on

6.

Three-dimensional solids have something that two-dimensional shapes do not. What is it?

[ ]	Variety

It is found in cubes, spheres, cylinders and pyramids for example

7.

[ ]	Line

A cube has six faces

8.

How many faces does a square-based pyramid have?

[ ]	3
[x]	5
[ ]	7
[ ]	9

A pyramid has 4 triangular faces and 1 square face

9.

If two lines are 'perpendicular', they are .......

10.

'Reflective or line', 'rotational' and 'plane' are all types of what?

[ ]	Angles
[ ]	Mirrors
[ ]	Prisms
[x]	Symmetry

Rotational symmetry means a 2-D shape can be rotated and still look the same, like a square
