The angles ACB, ADB stand on the same arc AB,the one being at the centre and the other at the Measure the number of degrees in each, and com-pare these numbers. Make the same constructions in the case of two orthree other circles, and repeat the measurements andcomparison. AMiat is your conclusion as to the size of the angleat the centre, compared with the size of the angle atthe circumference? 85 86 Geometry.
