WebThe circle is then called a circumscribed circle. If a right triangle is inscribed in a circle, then the hypotenuse is a diameter of the circle. Conversely, if one side of an inscribed triangle is a diameter, then the triangle is a right triangle, and the angle opposite the diameter is a right angle. Show Video Lesson Webfor the area of a triangle, an auxiliary line is drawn from a vertex perpendicular to the opposite side. Starting with Δ A , drop an altitude to the base of the triangle and label it h (for height). The formula for the area of a triangle is 1 2 A bh. Using right triangle trigonometry, sin(C)= ℎ 𝑎. Solving for h, h=a∙sin(C).
