Circle Geometry | Episode 10 - The Tan - chord Theorem (Angles in alternate segment)

📐 Alternate Segment Theorem (Tangent–Chord Theorem) Explained | Circle Geometry In this lesson, we explore the Alternate Segment Theorem, also known as the Tangent–Chord Theorem, one of the key circle geometry theorems tested in EGCSE / IGCSE Mathematics. 🔑 Short form: Angle between tangent and chord = angle in alternate segment 📘 Full statement: The angle between a tangent and a chord through the point of contact is equal to the angle subtended by the chord in the opposite arc of the circle. 🎯 In this video, you will learn: What a tangent and chord are How to identify the alternate segment in a diagram How to apply the theorem correctly in exam questions Common mistakes learners make and how to avoid them How this theorem links with angles in the same segment 📝 Exam tip: Always state the theorem clearly before using it as a reason when solving angle-chasing problems. 👨🏽‍🏫 Perfect for: Form 4 & Form 5 learners EGCSE / IGCSE exam revision Teachers looking for a clear teaching explanation 📌 Don’t forget to like, subscribe, and share with someone revising circle geometry! #CircleGeometry #AlternateSegmentTheorem #TangentChordTheorem #EGCSE #IGCSE #MathsRevision #AngleChasing
