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.
To Prove that a Figure is an Isosceles Triangle. ï«Prove that the triangle has two congruent sides using the distance formula. Ex. 1 Triangle QRS has vertices Q (-3, -3), R (0, 5), and S (3, -3). Prove using coordinate geometry. that QRS is an isosceles triangle. Step 1: Plot and label the triangle on the grid.
