WebDec 14, 2024 · Using the Tangent-Chord Theorem, we see that ∠ABC ≅ ∠ADB, so the two triangles are similar, and it follows that AB 2 =AC · AD. Proof Here's the proof of the Tangent-Secant Theorem: (1) ∠BAC ≅ ∠BAC //Common angle (2) ∠ABC ≅ ∠ADB // Tangent-Chord Theorem (3) ∠ACB ≅ ∠ABD // Sum of Angles in a Triangle (4) ΔABC∼ ΔADB //Angle … WebTangent, Cosecant, Secant, Cotangent. The tangent( in trigonometry) is defined as an angle in a right-angled triangle which has a ratio of perpendicular and base. The tangent of an …
