You can also use the given sides and angles to find the area of the triangle using Heron's formula or using trigonometric functions like Sin or Cos.

Once you find the sine of angle A, you can use the inverse sine function (arcsin) to find the measure of angle A in radians or degree. By solving this equation you can find the value of cos(C) and then use the inverse cosine function (arccos) to find the measure of angle C in radians or degree.Īdditionally, you can use the Law of Sines to find the measure of the angles, the formula is: Where c is the length of the non-congruent side, a is the length of the congruent sides, and C is the measure of the angle opposite side c. If you know the lengths of two congruent sides (a,a) and the length of the non-congruent side (c) of an isosceles triangle, you can use the Law of Cosines to find the measure of the angles. To calculate the properties of an isosceles triangle when given certain information, you can use the Pythagorean theorem, the Law of Cosines, or the Law of Sines. An isosceles triangle is a triangle where two sides have the same length. This calculator calculates any isosceles triangle specified by two of its properties.
