The part of the KS3 Maths syllabus that is commonly called 'Shapes' also deals with measurements. This quiz introduces you to some of the words you will need for this section. It will help in getting you started in the world of shapes.

Shapes can be 2 or 3 dimensional. Rectangles and squares are 2D shapes. We call them polygons and, because their angles are the same at each corner, we call them regular polygons. Cuboids, pyramids and cubes are 3D shapes, or polyhedrons. There are many words used to describe polygons and polyhedrons, such as angles, area, faces, radius and circumference. But what do these words mean? You will have learned about them in your classes; now test how much you have remembered.

Read each of the following questions carefully. Make sure that you understand them before choosing your answers. Good luck!

1.

Two lines are ....... if they're at right angles to each other.

perpendicular

intersecting

parallel

cylindrical

The walls of a house are perpendicular to its floor

2.

Two lines that are equidistant and not intersecting are known as what type of lines?

Geometric

Parallel

Simultaneous

Straight

Parallel lines never 'converge'

3.

Two lines that cross each other are said to what?

Intersperse

Interact

Intersect

Interrupt

Americans call crossroads intersections. That's because at a crossroads two roads cross each other and so intersect

4.

Why would you never talk about the capacity of a square?

Because only round objects have a capacity

Because squares are 2-dimensional objects

Because squares are too difficult to measure

Because squares are too small to have a capacity

2-dimensional (sometimes written as 2-D) objects are flat and therefore they don't have a capacity

5.

The 'perimeter' is the distance around the outside of a 2-D object. What might this be called in the case of a circle?

Circumference

Curcumference

Sircumference

Surcumference

The formula to calculate the circumference of a circle is π radius^{2}

6.

What is the meaning of the word 'capacity'?

The dimensions of an object

The weight of an object

The position of an object relative to the ground

The amount of space inside a hollow 3-dimensional shape

The capacity of a drinking glass is the amount of water it can hold when it is absolutely full

7.

Which of these cannot be measured against a continuous scale?

The mass of a bag of potatoes

The speed of a car

The population of a town

The temperature of a cup of tea

People are counted in whole numbers only. You can't have fractions of people

8.

The surface enclosed within a 2-dimensional shape such as a square or a circle is called its what?

Area

Arena

Circumference

Volume

To calculate the area of a rectangle, multiply its length by its width

9.

Which of the following might you find on a 'timetable'?

Arrival and departure times of buses

Number of cows in a field

Number of times that the telephone rings

Shopping days until Christmas

Timetables list events (such as train arrivals or school lessons) together with the time they will happen

10.

What word is commonly used for mass?

Dimension

Height

Length

Weight

'Mass' and 'weight' are often used interchangeably in maths questions
