Inscribed angle "V" and whose sides pass through points "A" and "B". Draw line "OA". Angle "BOA" is a central angle; call it "θ". Lines "OV" and "OA" are both radii of the circle, so they have equal lengths. Therefore, triangle "VOA" is isosceles, so angle "BVA" (the inscribed angle) and angle "VAO" are equal; let each of them be denoted as "ψ". Angles "BOA" and "AOV" are supplementary. They add up to 180°, since line "VB" passing through "O" is a straight line. Therefore, angle "AOV" measures 180° − "θ". It is known that the three angles of a triangle add
Degrees of the University of Oxford or Mathematics, or Mathematics and Computer Science, or Mathematics and Philosophy, or Physics, or Physics and Philosophy, is held together with a higher degree, the holder will rank in precedence equally with a person who holds the same higher degree together with the Degree of Master of Arts. Degrees of the University of Oxford The system of academic degrees at the University of Oxford can be confusing to those not familiar with it. This is not merely because many degree titles date from the Middle Ages, but also because many changes have been haphazardly introduced in recent years. For example,
