... Since x = 60°, triangle ABC is an equilateral triangle with sides all equal. The sides are all equal to 8. Perimeter of triangle ABC = 8 + 8 + 8 = 24. Triangle DEF has two angles equal, so it must be an isosceles triangle. The two equal sides will be opposite the equal angles. So, the length of D ...

... In this lesson, we will use the Law of Cosine to find the missing parts of a triangle in two cases: First, when given the lengths of two sides and the measure of the angle between them. Second, when given the lengths of all three sides. 3. Think of the Law of Cosines as a New and Improved Pythagorea ...
