The isosceles triangle theorem states that if two sides of a triangle are congruent, then the angles opposite those sides are ______________.A.proportionalB.supplementaryC.complementaryD.congruent

An altitude is drawn from the vertex of an isosceles triangle, forming a right angle and two congruent triangles. As a result, the altitude cuts the base into two equal segments. The length of the altitude is 11 inches, and the length of the base is 6 inches. Find the triangle’s perimeter. Round to the nearest tenth of an inch.
