An angle that turns through 1⁄360 of a circle is called a “one-degree angle,” and can be used to measure angles. an angle that turns through n one-degree angles is said to have an angle measure of n degrees. measure angles in whole-number degrees using a protractor. Sketch angles of specified measure.

• using the theorem that the angles in the same segment of a circle are equal. • using the theorem that the angle in a semi circle is a right angle. 34.1Angle subtended by an arc of a circle at the centre and the angles subtended on the circle O is the centre of a circle. If AB is a chord, it divides the circle into two parts.
