17.3 Translating shapes

17.3 Translating shapes

When you translate a shape you move it a given distance.
It can move right or le#, and up or down.

All the points on the shape must move the same distance in the
same direction.

Worked example 17.3

Translate this shape:
a 2 squares to the right and 3 squares up
b 5 squares to the left and 1 square down.

a image Pick one corner of the shape to translate fi rst. Move this corner
2 squares to the right and 3 squares up. Draw in the rest of the shape.

object
b Pick one corner of the shape to translate fi rst. Move this corner
5 squares to the left and 1 square down. Draw in the rest of the shape.

object

) Exercise 17.3

1 Copy each diagram then draw the image of the object, using the translation given.
a b c d

2 squares right 3 squares left 4 squares right 1 square left
2 squares down 4 squares up 1 square up 3 squares down

2 The diagram shows three triangles.
Describe the translation that takes: A In part c the translation doesn’t
a triangle A to triangle B B involve any movement left or
b triangle B to triangle C right, so you only need to give the
c triangle A to triangle C. c number of squares down.
