Describing rotations

The Maths Habit

Write the coordinates of the cross. Across, then up.

1(3, 2)

2(1, 4)

3(5, 3)

Shape A moves to shape B. Which one is a turn?

1

2

3

3. It turns upside down. In 1 it slides and in 2 it flips.

Rotation: A turn of a shape about a point.

Centre of rotation: The point the shape turns about. Here it is the cross.

180°: A half turn.

90° clockwise: A quarter turn, the way the hands of a clock go.

Is the description right? Thumbs up or thumbs down.

ARotation 180° about (5, 4)Yes

BRotation 90° clockwise about (2, 3)No: across first, so (3, 2)

CRotation 90° clockwise about (4, 3)No: it is a half turn, 180°

DRotation 90° clockwise about (4, 4)Yes

Answer sheet

A shape turns 90° anticlockwise. Which clockwise turn does the same?
270° clockwise
A half turn takes P (1, 4) to P′ (7, 4). Where is the centre of rotation?
(4, 4), halfway
P (6, 3) turns 180° about (4, 3). Where does P land?
(2, 3)
