Isosceles Triangle Vertex angle sin(β) = b/ 2a Isosceles Triangle Base angle sin(α) = h / a Isosceles Triangle Altitude alt = (b/2a) * √(4a² - b²) Isosceles Triangle Seimeperimeter s = a + (b/2) Isosceles Triangle Height h = (1/2) * √(4a² - b²) Isosceles Triangle Area K = (1/4) * b * √( 4 * a² - b² ) The base length of an isosceles triangle b = 8 cm The side length of an isosceles triangle a = 5 cm The obtained value is the sine function of the vertex angle.Įxample 1: Find the unknown measures of an isosceles triangle? If the side length and base length of the triangle is 5 cm, 8 cm respectively.².Divide the base length by twice of side length.Check out the base length and side length from the question.Divide the height by side length to get the sine function of the base angle.Get height, a side length of the triangle.Divide the result by 2 to get the height of a triangle.Apply square root to the subtracted value.Multiply the side length with 4 and subtract it from the base square. Square the common side length and base length.Check isosceles triangle base, side length.Multiply the result of step 3, step 4 to get altitude.Divide the base by 2 times of side length.Apply the square root function to the result.Multiply the square of side length with 4 and subtract it from the square of the base.
