Where should an ice-cream parlor be set? up so that maximum number of persons can approach it?

[Hint The parlour should be equidistant from A, B and C.]

Answer :

Let us join A and B, and draw l, the perpendicular bisector of AB.

Now, join B and C, and draw m, the perpendicular bisector of BC. Let the perpendicular bisectors l and m meet at O.
The point O is the required point where the ice cream parlour be set up.

Note: If we join A and C and draw the perpendicular bisector, then it will also meet (or pass through) the point O.

- 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.
