The incenter is the one point in the triangle whose distances to the sides are equal.

If the triangle is acute, then the incenter is also located in the triangle's interior.
3yrs. kumu(moderator)(m). You draw a radius to a vertex next to the apothem. That creates a right triangle with the apothem as one leg, half a side length is the other leg, and the radius is the hypotenuse. Typically, you know the length of a side and can find the measure of a central angle (360/#sides). The angle in the triangle will be half that. Then you have to use the tangent ratio to determine the apothem.
