GCSE Transformations of Shapes
Name:
Translations
Translations are usually given in vector form: ()
means 3 units to the right and 1 unit down.
So what does
mean?
What is the vector translating A to B?
B to A?
What is the effect of a translation?
Now translate shape C with vector
|. Label the image C'.
Translate shape P with vector
and shape Q with vector
What vector would translate each shape back to its original
position?
P:
Q:
Can you see how the coordinates of the vertices (corners) change?
If you were to translate the point (2, 3) with vector
), where
would it move to?
Reflections
1. Reflect shape S in the line y = 0.
2. Reflect shape Tin the line x = 2.

Reflections
1. Reflect shape S in the line y = 0.
2. Reflect shape T in the line x = 2.
3. Now reflect shape T in the line y = x.
Spare grids in case you need them:
What is the image of:
(a) the point (2, 3) reflected in the line x = 0?
(b) the point (2, 3) reflected in the line y = 0?
(c) the point (2, 3) reflected in the line y = x?
Rotation
1. Rotate shape A (a) clockwise through 90° about the origin; (b) clockwise through 180° about the origin.
2. Rotate shape D anticlockwise through 90° about the point (2,-1).
D.

- Find a unit vector perpendicular to c = (3, 4, −7) and d = (−1, −1, 3). Give an exact answerarrow_forwardA bagel shop sells different kinds of bagels: onion, chocolate chip, sunflower, and wheat. The selling price for all bagels is $0.50 except for the chocolate chip which are $0.55. 1. How can we represent this information as a vector? Call this result P. 2. Each bagel costs a different amount to produce. We can display this information in an expense vector E = (0.32, 0.38, 0.29, 0.27). Let I = (I,I2, I3, I4) be the inventory vector which lists the number available of each kind of bagel and let C = (C1, C2, C3, C4) represent the consumption vector (ie, the vector listing the number of bagels sold each day). What do the following expressions mean? 1.Ỉ - Ở II. C – 0.81 III. P – Ẻ 3. How could you compute the revenue (ie, gross income) for the day? 4.
