1. Any angle inscribed in a semicircle must be a right angle. 2. If the central angle of a sector with radius 10 measures 60°, then the area of the sector is 5/3 square inches. 3. The measure of an inscribed angle, ?A, in a circle is twice the measure of a second inscribed angle, ?B, in the same circle. Then the arc intercepted by ?A is twice as long as the arc intercepted by ?B. 4. If P is the midpoint of chord AB in circle O, then ?OPB = 90°.
