The Maths Prof: Finding Equation of a Perpendicular Bisector

In this lesson I show you how to find the equation of a perpendicular bisector of a line segment. ✨✨Steps to follow below✨✨ 1. Find the gradient of the line AB 2. Find the gradient of the perpendicular bisector 3. Find the midpoint of the line AB 4. Find the y-intercept of the perpendicular bisector (using the midpoint coordinates and the gradient already found) 5. Write down the equation of the perpendicular bisector! 😊 Related lessons which you may find useful👇 🌟 Finding the gradient of straight lines    • The Maths Prof: Finding Gradients of Strai...   🌟 Parallel & Perpendicular Lines    • The Maths Prof: Parallel & Perpendicular L...   🌟 Finding midpoints of straight lines    • The Maths Prof: Finding Midpoints of Strai...   🌟 Finding equations of straight lines    • The Maths Prof: Finding Equations of Strai...   I hope that you find the lesson helpful.
