WALT: Geometry Translations

2. Translations 4 3 -5 -4 y My translation is Right 4 and Up 32 4 5 6 7 8 9 10 1 -1 -2 -3 -4 -5 -6 -7 -8 -9
-10 3 c’
My translation is Right 4 and Up 3 c
We write this as: a’ b’ 4 3
x direction
y direction a b x g
My next translation is Left 5 and Down 4 f
We write this as: d e g’ f’ -5 -4
x direction
y direction d’ e’

3. Translations Rectangle abcd does a translation of 6 -32 4 5 6 7 8 9 10 1 -1 -2 -3 -4 -5 -6 -7 -8 -9

Rectangle abcd does a translation of 6 -3 d c
What are the co-ordinates of
a’ b’ c’ and d’ ? a b
a’ = (-1, -1)
b’ = (2, -1)
c’ = (2, 4)
d’ = (-1, 4)
