Copy the triangle in each of the following figures on squared paper. In each case, draw the line(s) of symmetry, if any and identify the type of triangle. (Some of you may like to trace the figures and try paper-folding first!)

(a) It is an isosceles triangle. There will be only 1 line of symmetry.
(b) It is an isosceles triangle. There will be only 1 line of symmetry.
(c) It is a right-angled triangle. There will be only 1 line of symmetry.
(d) It is a scalene triangle. There will be no line of symmetry.
