Knowing position involves being able to read the coordinates of shapes on a grid. Coordinates are used for map reading and also in knowing where to place a specific point on a grid. But how do the coordinates change when shapes are rotated or reflected? Working out the new coordinates of a rotated shape can be difficult without a pencil and paper!

See how much you remember from your math classes by trying this quiz all about position.

1.

If a triangle has a 60^{o} angle and a 40^{o} angle what angle is the third corner?

60^{o}

70^{o}

80^{o}

90^{o}

2.

A shape has the coordinates (5,1) (1,4) (5,6) (9,4). What shape is it?

Square

Rectangle

Rhombus

Kite

It can be hard to imagine coordinates in your head. Drawing on some paper might help you to visualize the shape

3.

What do the angles of a triangle total?

180^{o}

360^{o}

200^{o}

90^{o}

No matter what lengths its sides are or what shape it is, the angles in a triangle always add up to 180^{o}

4.

What is the intersection?

The point where two angles meet

The point where two coordinates meet

The point where two shapes meet

The point where two lines meet

Where two roads meet it is also called an intersection

5.

What is used to measure angles?

Ruler

Protractor

Tape measure

Compass

Most protractors are semi-circles divided into 180^{o}

6.

What is the total size of the other two angles in a right angled triangle?

30^{o}

45^{o}

60^{o}

90^{o}

180^{o} - 90^{o} = 90^{o} so the other two angles must add up to that

7.

A rectangle has the coordinates (2,2) (2,4) (6,4). What is the fourth coordinate?

(2,6)

(6,2)

(1,6)

(4,6)

This rectangle would have its longest sides at the top and bottom

8.

What do we call two lines that cross one another?

Intersecting

Friends

Meeting

Crisscross

Intersecting lines meet but parallel lines never do

9.

If I turn 60^{o} how much more do I need to turn to complete one full turn?

100^{o}

200^{o}

300^{o}

400^{o}

360^{o} - 60^{o} = 300^{o}

10.

A triangle has the coordinates (1,1) (1,4) (4,1). What will the coordinates be after a quarter turn clockwise?

(1,1) (4,1) (1,-2)

(1,-1) (4,1) (1,-4)

(1,1) (4,1) (1,4)

(1,1) (4,1) (4,-4)

If you worked that out without drawing on some paper then very well done!

^{o}+ 40^{o}= 100^{o}so 180^{o}- 100^{o}= 80^{o}
