Suppose the base of the triangle is of length x cm and the equal sides are of length y cm. read more
Any type of triangle will have angles that add up to 180o. yet two angles of an isosceles triangle are equal. read more
For instance, the area of a triangle can be computed using Heron's formula, which requires all sides and the semiperimeter as given. The lengths of the sides, in conjunction with the measurements of the angles, are also important factors in triangle geometry, inequalities and trigonometry. read more
