The 13 pages that link to Central angle, each with the reason it gives.

• RadianRelated: Its intercepted arc supplies the length used to measure the angle in radians.

• Great circleRelated: Its measure converts angular separation along a great circle into arc length.

• Inscribed angle theoremRelated: Its measure is twice that of an inscribed angle subtending the same arc.

• Regular polygonRelated: Joining the center to adjacent vertices divides a regular polygon into equal central angles.

• DiameterRelated: A straight central angle spans a semicircle and subtends a diameter.

• Spherical trigonometryRelated: A spherical arc’s length is naturally related to its central angle.

• ChordRelated: It determines the length of the chord between its endpoints.

• Great-circle distanceRelated: The distance equals the sphere’s radius multiplied by the central angle in radians.

• Spherical law of cosinesRelated: It measures each spherical side as an angle at the sphere’s center.

• Pie chartRelated: Each sector’s central angle is its fraction of the total multiplied by 360 degrees.

• MilliradianRelated: The milliradian measures the central angle associated with a short circular arc.

• Constant chord theoremRelated: A central angle measures its intercepted arc directly, clarifying the arc comparison behind the theorem.

• Van Schooten's theoremRelated: The central angles subtending the sides of an equilateral triangle are each 120 degrees.
