Secant-Tangent Angles: Half Difference of Arcs Geometry Tutorial

Описание: Learn how to calculate the angle formed by a Secant and a Tangent intersecting outside a circle! 📐✨

In this geometry lesson, we break down the "Half Difference of Arcs" theorem. We'll start with the definitions of secant and tangent lines, explain the formula clearly, and walk through two full examples—one finding the angle, and one working backwards to find an arc.

Perfect for high school geometry students or anyone reviewing circle theorems. 🧠

Topics Covered:
🔹 Definition of Tangent vs Secant
🔹 The Exterior Angle Theorem Formula
🔹 Step-by-step practice problems
🔹 Common tips to avoid mistakes
