Vertex angle is the angle between the legs and the angles with the base as one of their sides are called the base angles. In an isosceles triangle the sides that are directly across from the congruent angles are also congruent. Find a missing side length on an acute isosceles triangle by using the Pythagorean theorem.
Since we have an isosceles triangle we know that there are 2 equal sides So EITHER the missing side has length 15 to give us a 15-15-22 triangle OR the missing side has length 22 to give us a 15-22-22 triangle. 2 sqrtL2 - A2 where L is the length of the other two legs and A is the altitude of the triangle. To find the perimeter add up all the sides.
Because the legs are of equal length the base angles are also identical. The height of an isosceles triangle is the perpendicular line segment drawn from base. To find an unknown side of a triangle you must know the length of other two sides andor the altitude.
