Question
Use graph sheet for this question. Take 2 cm = 1 unit along the axes.
- Plot A(0, 3), B(2, 1) and C(4, –1).
- Reflect point B and C in y-axis and name their images as B' and C' respectively. Plot and write coordinates of the points B' and C'.
- Reflect point A in the line BB' and name its images as A'.
- Plot and write coordinates of point A'.
- Join the points ABA'B' and give the geometrical name of the closed figure so formed.
