In a triangle locate a point in its interior which is equidistant from all the sides of the triangle.
Solution:
The point which is equidistant from all the sides of a triangle is called the incentre of the triangle.
The incentre of a triangle is the intersection point of the angle bisectors of the interior angles of that triangle.
Here, in ∆ABC, we can find the incentre of this triangle by drawing the angle bisectors of the interior angles of this triangle. I is the point where these angle bisectors are intersecting each other.
Therefore, I is the point which is equidistant from all the sides of ∆ABC that is IP = IQ = IP.
