The central angle AOB O Find the area of the triangle AOB Find the area of the sector AOB Area of minor segment = Area of A sector – area of triangle B Answer: 10.3 square centimeter. OTHER MATHEMATICS TOPIC NOTES ... WebProof: To prove this theorem, let \ACB be an inscribed angle of O. We must prove that m\AOB = mùAB = 1 2 \ACB There are three possible cases we need to consider, the case where the center of the circle, O, is outside of the angle \;ACB; another case is where O is inside of \ACB. The third case is if center O is on one of the side of \ACB. We prove

WebIn the circle with center O above, sector AOB, shaded in gray, is bounded by radii OA and OB, and arc AB. Central angles and sectors. A central angle is an angle whose vertex is the center of a circle. The two sides of a central angle are radii of the circle. The central angle is subtended by an arc, creating the sector of the circle.
