WebAngle Theorems. a) The angle at the circumference subtended by a diameter is 90°. This is usually stated as ‘The angle in a semicircle = 90°’. The lines OA, OP and OB are equal (radii of circle). Triangles and are … WebThe angle of the diameter (180 °) is the central angle that subtends the arc represented by half the circumference. Tracing a triangle with the diameter being one of the sides, we would automatically form an inscribed angle that also subtends the same arc as the angle of the diameter. Thus, that inscribed angle would be half of 180 ° (90 ...
