Isosceles Triangle - Definition, Angles, Properties, Examples

WebThe area of an isosceles triangle is given by the following formula: Area (A) = ½ × base (b) × height (h) The perimeter of the isosceles triangle is given by the formula: Perimeter (P) = 2a + base (b) Here, ‘a’ refers to the length of the equal sides of the isosceles triangle and ‘b’ refers to the length of the third unequal side. Solved Examples WebLet E, F, and G be the points where the angle bisectors of C, A, and B cross the sides AB, AC, and BC, respectively. Using the angle sum property of a triangle, we can calculate the incenter of a triangle angle. In the above figure, ∠AIB = 180° – (∠A + ∠B)/2. Where I is the incenter of the given triangle.
