Year 6 Geometry Post-Assessment Quiz

You have been asked to draw a quadrilateral where at least one of its sides is 9cm long.

Which shape could you not draw?

• A

• B

• C

• D

What is the mathematical name for this 3-D shape?

• A box shape

• Rectangle

• Cube

• Cuboid

Only one of these nets will make a cylinder. Which is it?

• A

• B

• C

• D

What is the size of angle A in this triangle?

• It is impossible to work out the answer without using a protractor.

• 129°

• 51°

• 231°

Can you calculate the size of angle B without measuring it with a protractor?

• Yes. B = 258°

• Yes. B = 78°

• No. The only way to find B is by using a protractor.

• Yes. B = 98°

A farmer’s field is a regular hexagon. A cow is standing in the centre and looking

at the gate.

It turns clockwise to look at the tree. Through how many degrees has it turned?

• 360°

• 60°

• 4°

• 240°

These are both straight lines.

Which of these statements about angle B is true?

• The only way to find out angle B is if angles A and C were labelled.

• Angle B is 69⁰

• Angle B is 111⁰

• The only way to find out angle B is if we measure it using a protractor.

Look carefully at this rectangle.

Which of these statements is true?

• It is impossible to know what the coordinates of the top right corner of the

  rectangle are because there is no grid and the axes are not labelled.

• The coordinates of the top right corner of the rectangle are (1, 5).

• The coordinates of the bottom right corner of the rectangle are (2, 8).

• The coordinates of the bottom right corner of the rectangle are (5, 1).

Claire is thinking about whether this is a net of a 3D shape.

Which of these statements is true?

• This is a net. It will make a triangular prism when it is folded.

• This is a net. It will make a triangular-based pyramid when it is folded.

• This is not a net. It is impossible to fold it into a 3-D shape.

• This is a net. It will make a square-based pyramid when it is folded.

Keisha has drawn this quadrilateral.

She wants to find out the unknown angle D

in the bottom left corner of the shape.

There are several ways she can find the answer if she knows

some of the other angles.

Which of these methods will NOT give Keisha the

right answer?

• The interior angles of a quadrilateral always add up to 360⁰.

  So, if Keisha

  knows what angles A, B and C are, she can subtract them all from 360

  and be left with angle D.

• Opposite angles are the same. If Keisha knows what angle B is, angle D

  will be the same.

• A complete turn equals 360⁰. So, if Keisha knows what angles E, F and G

  are, she can subtract them all from 360 and be left with angle D.

• There are 180⁰ in a straight line. Angles D and G are make a straight line

  together, so if Keisha knows what angle G is, she can subtract it from 180

  and be left with angle D
