(i) Image of point A (- 5,4), when reflected in y-axis, is B whose co-ordinates will be (5,4)
(ii) Image of B (5, 4), when reflected in origin, is C whose co-ordinates will be (- 5, – 4)
(iii) Image of A (- 5,4) in x-axis is C whose co-ordinates are (- 5, – 4)

Draw the line(s) of symmetry for the figure drawn below:
Draw all the possible lines of symmetry for the given figure below:
A shape has reflection symmetry if it has a line of symmetry
Look at the figure in the white box. On which of the dotted lines will you keep the mirror so that you get shape (b)? Also, tell which part of the picture will be hidden when we keep the mirror on the dotted line.
Copy the following drawing on squared paper. Complete such that the resulting figure has two dotted lines as two lines of symmetry.
How did you go about completing the picture?
