Σελίδα 2 - BAC shall be a right angle; and the angle in the segment ABC, which is greater than a semicircle, shall be less than a right angle ; and the angle in the segment ADC, which is less than a semicircle, shall be greater than a right angle. Join AE, and produce BA to F.
Σελίδα 3 - ABC must be less than a right angle : and therefore the angle in a segment ABC greater than a semicircle, is less than a right angle. And...
Σελίδα 1 - The angle in a semicircle is a right angle; the angle in a segment greater than a semicircle is less than a right angle; and the angle in a segment less than a semicircle is greater than a right angle.
