It is an activity.

We require 150 equilateral triangles of side 1 cm in the Fig. (i) and 300 equilateral triangles in the Fig. (ii).
\(\therefore \)The Fig. (ii) has more triangles.

- ABC is a triangle. Locate a point in the interior of \(\triangle \) ABC which is equidistant from all the vertices of \(\triangle \)ABC.
- In a triangle locate a point in its interior which is equidistant from all the sides of the triangle.
- In a huge park, people are concentrated at three points (see figure) A: where these are different slides and swings for children. B: near which a man-made lake is situated.
