A point starts at the location (4,0)(4,0) and travels 11.2 units CCW along a circle with a radius of 4 units that is centered at (0,0)(0,0). Consider an angle whose vertex is at (0,0)(0,0) and whose rays subtend the path that the point traveled. Draw a diagram of this to make sure you understand the context. What is the radian measure of this angle? radians What is the degree measure of this angle? degrees
Angles in Circles
Angles within a circle are feasible to create with the help of different properties of the circle such as radii, tangents, and chords. The radius is the distance from the center of the circle to the circumference of the circle. A tangent is a line made perpendicular to the radius through its endpoint placed on the circle as well as the line drawn at right angles to a tangent across the point of contact when the circle passes through the center of the circle. The chord is a line segment with its endpoints on the circle. A secant line or secant is the infinite extension of the chord.
Arcs in Circles
A circular arc is the arc of a circle formed by two distinct points. It is a section or segment of the circumference of a circle. A straight line passing through the center connecting the two distinct ends of the arc is termed a semi-circular arc.
