In the sketch O is the centre of the circle and AOB is a diameter. Therefore arc ACB is a below.: Measure C and record your value in the table semi-circle, and C is an angle in a semi-circle. Now follow the following steps to draw and measure two more angles in semicircle ACB: Choose any other point on semicircle ACB and name it point D. Draw AD and BD. Measure D. Choose a third point on semicircle ACB and name it point E. Draw AE and BE. Measure E. Angle Size 12 is equal to 90
