Geometry calculator circles and angles
WebSum of central angles in a circle = 360 º. 80º + 120º + x = 360º. Simplify. 200º + x = 360º. Subtract by 200 º on both sides. x = 160 º. Hence, the measure of the missing central … WebConstruct a tangent line to a circle. Construct an equilateral triangle inscribed in a circle. 20. Construct a square inscribed in a circle. 21.
