*An inscribed angle is an angle formed by two chords in a circle, with its vertex on the circle’s circumference. The measure of an inscribed angle is half the measure of the arc it intercepts. To find the arc length, you can use the formula: Arc Length = (Angle Measure / 360 degrees) x (2πr), where r is the circle’s radius.*
