In an isosceles triangle, the base angles have the same degree measure and are, as a result, equal (congruent). Similarly, if two angles of a triangle have equal measure, then the sides opposite those angles are the same length. read more

Substitute the known values of the isosceles triangle into the formula. For instance, if the base of the isosceles triangle is 8 cm and the height is 26 cm, then the equation is area = 1/2 (8 x 26). Solve the equation for the area. read more

The base of the triangle is 12 cm long; the lateral side is 19 cm long. Problem 5 Find the measures of the isosceles triangle sides, if the lateral side is in two times longer than the base and the perimeter of the triangle is 30 cm. Solution Let x be the length of the base of the triangle (in centimeters). read more
