- Q.1 Copy the figures with punched holes and find the axes of symmetry for the following:
- Q.2 Give the line(s) of symmetry, find the other hole(s):
- Q.3 In the following figures, the mirror line (i.e., the line of symmetry) is given as a dotted line. Complete each figure performing reflection in the dotted (mirror) line. (You might perhaps place a mirror along the dotted line and look into the mirror for the image). Are you able to recall the name of the figure you complete?
- Q.4 The following figures have more than one line of symmetry. Such figures are said to have multiple lines of symmetry. Identify multiple lines of symmetry, if any, in each of the following figures:
- Q.5 Take any one diagonal as a line of symmetry and shade a few more squares to make the figure symmetric about a diagonal. Is there more than one way to do that? Will the figure be symmetric about both the diagonals?
- Q.6 Copy the diagram and complete each shape to be symmetric about the mirror line(s).
- Q.7 State the number of lines of symmetry for the following figures: (?) An equilateral triangle (b) An isosceles triangle (c) A scalene triangle (d) A square (e) A rectangle (f) A rhombus (g) A parallelogram (h) A quadrilateral (i) A regular hexagon (j) A circle
- Q.9 Give three examples of shapes with no line of symmetry.
- Q.10 What other name can you give of the line of symmetry of (a) an isosceles triangle? (b) a circle?
