Tangent theorem

WebSep 4, 2024 · Theorem \(\PageIndex{2}\) A line perpendicular to a radius at a point touching the circle must be a tangent. In Figure \(\PageIndex{3}\), if \(OP \perp \overleftrightarrow{AB}\) then \(\overleftrightarrow{AB}\) must be a tangent; that is, \(P\) … WebOct 1, 2024 · The Tangent-Chord theorem is sometimes stated as "The angle formed by a tangent to a circle and a chord is equal to half the angle measure of the intercepted arc." This is equivalent to what we have shown, since the angle measure of an intercepted arc is twice the angle measure of the inscribed angle that subtends it.
