Question

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

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

2) Reflect the points B, C, D and E on the y-axis and name them respectively as B', C', D’ and E'.

3) Write the coordinates of B', C', D' and E'.

4) Name the figure formed by B C D E E' D' C' B'.

5) Name a line of symmetry for the figure formed.

2. Reflect the points B, C, D and E on the y-axis and name them respectively as B', C', D’ and E'.
3. Write the coordinates of B', C', D' and E'.
4. Name the closed figure formed.

 

Answer 1

1) See the figure

2) Reflection of points on the y-axis will result in the change of the x-coordinate

3) Points will be B’(−2, 5), C’(−5, 2), D’(−5, −2), E’(−2, −5).

4) The figure BCDEE’D’C’B’ is a octagon.

5) The lines of symmetry are x-axis or y-axis.
