Question

Use a graph paper for this question taking 2 cm = 1 unit along both axes.

1. Plot A(1, 3), B(1, 2) and C(3, 0).
2. Reflect A and B on the x-axis and name their images as E and D respectively. Write down their coordinates.
3. Reflect A and B through the origin and name their images as F and G respectively.
4. Reflect A, B and C on the y-axis and name their images as J, I and H respectively.
5. Join all the points A, B, C, D, E, F, G, H, I and J in order and name the closed figure so formed.

Answer 1

1. 
   
2. Image of A and B on the x-axis is E(1, –3), and D(1, −2) respectively.
3. Image of A and B through the origin is F(−1, −3), and G(–1, –2) respectively.
4. Image of A, B and C on the y-axis is J(–1, 3), I(−1, 2) and H(−3, 0) respectively.
5. Closed figure is a decagon shape.
