Movement Proof: We will do the same as with our movement proof for the inscribed angle theorem. Study two examples of the tangent chord theorem with a walkthrough of their proofs. , ∠ACB) is equal to the angle between the tangent at A and the chord AB (i. The formula for calculating this angle is Theorem 1 The measure of the angle between a chord and a tangent line to a circle at the endpoint of the chord is half the measure of the arc stretched by the chord. Courses on Khan Academy are always 100% free. What Do You Mean by the Alternate Segment Theorem ? Alternate Segment Theorem is also known as tangent-chord theorem. In this Mathematics video, we go through the Euclidean Geometry proof for the Tan Chord Theorem. and a chord close chordA straight line joining two points on a circle is a chord. Learn key theorems, concise proofs, derivations, and practice problems for circle geometry. A tangent is perpendicular to the radius (OT ⊥ ST), drawn at the point of contact with the circle. Start with the case of the angle formed by two intersecting chords. If a straight line touch a circle, and from the point of contact there be drawn across, in the circle, a straight line cutting the circle, the angles which it makes with the tangent will be equal to the The converse theorem states that if the angle between a line and a chord equals the angle subtended by the chord in the alternate segment, then the line is a tangent to the circle.
