Inscribed angle theorem proof (article) Khan Academy

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 ... WebThe equality of vertically opposite angles is called the vertical angle theorem.
