Video Tutorial on Finding the Side Length of a Right TriangleA triangle is a form of a polygon with three sides or edges and vertices. A polygon is a two dimensional, closed, and flat with multiple corners. Sides of a triangle form the basic shape in geometry. Ideally, A, B, and C are used to denote three sides. The sum of three angles forms the interior angles in this shape which is 180 degree. 2. Divide the isosceles into two right triangles. Draw a line down from the vertex between the two equal sides, that hits the base at a right angle. You now have two equal right triangles. This line divides θ perfectly in half. Each right triangle has an angle of ½θ, or in this case (½) (120) = 60 degrees. 3.Answer (1 of 4): To solve an SSS triangle: * use The Law of Cosines first to calculate one of the angles * then use The Law of Cosines again to find another angle * and finally use angles of a triangle add to 180° to find the last angle.
