Question

Use a graph paper for this question taking 1 cm = 1 unit along both the x and y axis :

(i) Plot the points A(0, 5), B(2, 5), C(5, 2), D(5, -2), E(2, -5) and F(0, -5). 

(ii) Reflect the points B, C, D and E on the y-axis and name them respectively as B’, C’, D’and E’ 

(iii) Write the coordinates of B’, C’, D’and E’. 

(iv) Name the figure formed by BCDE E’D’CR’. 

(v) Name a line of symmetry for the figure formed.

Answer 1

(i) See diagram below.

(ii) Coordinates: B’ (-2, 5), C’ (-5, 2), D’ (-5, -2), E’ (-2, -5) 

(iii) Octagon 

(iv) x-axis or y-axis.
