Find the measure of a circle
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 angle is 160 degrees. Example 4. WebMar 26, 2024 · Measure out and draw a set of crossed lines inside of a circle to pinpoint the center. Sketch two separate sets of overlapping circles to identify the exact center point. Draw a square snugly around the circle. Sketch an "X" between all 4 corners of the square to find the circle's center. Method 1.
