Shapes are a very important part of maths and you will need to learn their names and their properties. Most shapes you come across are regular polygons, such as squares, hexagons and circles. But these are all 2-D shapes. You’ll also encounter 3 dimensional ones like cubes, cylinders and spheres.

This is the second of our Very Easy Eleven Plus maths quizzes on shapes. If you have already played the first then this one should be a doddle. Have a go and see if you can score ten out of ten.

Before you start, make sure that you read each question carefully and fully understand it before you pick your answer. Once you’ve mastered this, then move on to the next quiz. After all, the more practice you get with shapes, the better you will understand them and the more successful you will be in your exams. Good luck!

1.

The internal angles of a triangle always add up to how many degrees?

90^{o}

180^{o}

270^{o}

360^{o}

2.

How many corners and faces does a cube have?

8 corners and 6 faces

12 corners and 6 faces

6 corners and 8 faces

12 corners and 8 faces

Cubes are like 3-D squares. They have 8 corners (vertices), 6 faces (facets), and 12 edges

3.

What do we call a line which cuts a circle in half and passes through its centre?

Radius

Diameter

Circumference

Arc

The radius is half the diameter from the centre to the edge. The circumference is the distance around a circle, like the perimeter of other shapes. An arc is a part of the circumference

4.

How many sides does a quadrilateral have?

Three sides

Four sides

Six sides

Eight sides

Quadrilaterals have four sides (edges) and four corners (vertices). Squares and rectangles are both quadrilaterals

5.

What do we call a triangle with one right-angle corner?

A square triangle

A half-square triangle

A right-angled triangle

A perfect triangle

There are lots of different types of triangle besides right-angled: equilateral, isosceles, scalene, acute and obtuse. You don’t need to know about all of these yet – but you will do much better at secondary school if you learn them early

6.

A parallelogram whose sides are the same length is often called a ‘diamond’. What is another name for a ‘diamond’ shape?

Square

Trapezium

Kite

Rhombus

A rhombus is like a squashed square, and a parallelogram is like a squashed rectangle. Trapeziums have just one set of parallel sides

7.

What do we call a 3-D shape with straight parallel sides and a circular top and bottom?

A sphere

A prism

A pyramid

A cylinder

Cylinders are everywhere: tin cans, rolling pins, pipes, candles, torches, toilet rolls, pencils, straws… the list goes on!

8.

What is another term for a 3-D shape?

A solid

A polygon

A quadrilateral

A vertex

3-D shapes are also known as solids. Solids have volume whilst 2-D shapes are ‘flat’

9.

Which 2-D shape has seven sides which are equal in length and joined at the same angle to each other?

A regular pentagon

A regular hexagon

A regular heptagon

A regular octagon

If the sides weren't all the same length, it would be called an 'irregular' heptagon. Polygons are closed shapes that have three or more straight sides: pentagon (5 sides), hexagon (6 sides), heptagon (7 sides), octagon (8 sides), nonagon (9 sides), decagon (10 sides). Try to remember these if you can

10.

Which of the following shapes is not a quadrilateral?

A rectangle

A square

A cube

A rhombus

Cubes are 3-D shapes. Quadrilaterals are 4-sided, 2-D shapes
