A central angle is an angle that forms when two radii are drawn from the center of a circle out to its circumference. There are a number of equations used to find the central angle, or you can use the Central Angle Theorem to find the relationship between the central angle and other angles.

Central angles This lesson offers a concise, but thorough explanation of central angles, but also of arcs and sectors of a circle Definition: An angle is a central angle if it meets the following two conditions 1) The vertex of the angle is located at the center of a circle. 2) The rays that make up its sides are radii of the circle. Below, find an illustration of the definition above: You can.
Find the central angle. Make an isosceles triangle with the central angle and the given side length. Create 2 right triangles from the isosceles triangle. Use right angle trigonometry to calculate the area of one of the two right triangles. Then multiply that by the number of congruent right triangles within the polygon. Check the math notes for more information.
