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? 
Solution:
We draw a line passing through the centre point to each shape, in order to check their symmetry.
(a)The shape formed is a square.
(b)The shape formed is a triangle.
(c)The shape formed is a rhombus.
(d)The shape formed is a circle.
(e)The shape formed is a pentagon.
(f)The shape formed is an octagon
