To calculate the base of an isosceles triangle, you need either the length of one of the equal sides and the vertex angle or the length of both equal sides and the vertex angle. If you have the length of one equal side and the vertex angle, you can use trigonometric functions such as sine, cosine, or tangent to find the length of the base. If you have the length of both equal sides and the vertex angle, you can use the Law of Cosines to find the length of the base.
