Web8.2 Circle geometry (EMBJ9). Terminology. The following terms are regularly used when referring to circles: Arc — a portion of the circumference of a circle.; Chord — a straight line joining the ends of an arc.; Circumference — the perimeter or boundary line of a circle.; Radius (\(r\)) — any straight line from the centre of the circle to a point on the … WebStep 2: Use what we learned from Case A to establish two equations. In our new diagram, the diameter splits the circle into two halves. Each half has an inscribed angle with a ray on the diameter. This is the same situation as Case A, so we know that. (1)\quad\purpleC {\theta_1}=2\blueD {\psi_1} (1) θ1 = 2ψ1. and. WebThe following two theorems directly follow from Theorem 70. Theorem 71: If two inscribed angles of a circle intercept the same arc or arcs of equal measure, then the inscribed angles have equal measure. Theorem 72: If … how does fireball work on pick 3
