WebThe tangent-secant theorem can be proven using similar triangles (see graphic). Like the intersecting chords theorem and the intersecting secants theorem , the tangent-secant theorem represents one of the three basic cases of a more general theorem about two intersecting lines and a circle, namely, the power of point theorem .

WebDec 4, 2024 · An angle formed by an intersecting tangent and chord has its vertex “on” the circle. ∠ABC is an angle formed by a tangent and chord. Its intercepted arc is the minor arc from A to B. m∠ABC = 60° 4. Angle … WebNov 28, 2024 · Chord/Tangent Angle Theorem: The measure of an angle formed by a chord and a tangent that intersect on a circle is half the measure of the intercepted arc. Figure 6.16. 1 m ∠ D B A = 1 2 m A B ^ If two angles, with their vertices on the circle, intercept the same arc then the angles are congruent. WebSep 28, 2024 · Angle created by a tangent and chord Before we get to my botched drawing, think about a tangent line and a diameter. These lines are perpendicular, so we know the angle is 90 degrees. marks and spencer candles
