Copy the triangle in each of the 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!)

Solution:

We will be using the concepts of the line of symmetry to solve this.

Symmetry states that one shape is identical to the other shape when it is moved, rotated, or flipped.

(a) It is an isosceles triangle having one symmetric line.

(b) This figure is an isosceles triangle having only one symmetric line.

(c) It is an isosceles right-angled triangle that has only one symmetric line.

(d) It is a scalene triangle. It has no line of symmetry.
