Ans : The axes of symmetry in the given figures are as follows.
Q.2: 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?
Ans : The given figures can be completed as follows.
Q.3: 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:
Ans : (a) The given figure has 3 lines of symmetry. Hence, it has multiple lines of symmetry. (b) The given figure has 2 lines of symmetry. Hence, it has multiple lines of symmetry. (c) The given figure has 3 lines of symmetry. Hence, it has multiple lines of symmetry.
