Perpendicular Lines and the Equation of a Tangent
Perpendicular lines in GCSE Maths are two lines that intersect at a right angle, or 90 degrees. The gradient of one line is the negative reciprocal of the gradient of the other line, meaning that the product of their gradients is -1. Perpendicular lines can be identified by examining their equations or their graphical representation in a coordinate plane. We will also investigate how to find the equation of a tangent using perpendicular lines.
After watching the AJMaths revision videos on Perpendicular Lines and the Equation of a Tangent I will be able to:
- Find Examples of Perpendicular Lines
- Find the Equation of Perpendicular Bisectors
- Find the Equation of Tangents Using Perpendicular Lines
- Answer Exam Style Questions on Perpendicular Lines and the Equation of a Tangent for GCSE Maths
Introduction to Perpendicular Lines
In this video we will recap what we have previously learned about perpendicular lines.
Finding the Equation of a Tangent Using Perpendicular Lines
In this video we will take a look at how we can find then equation of a tangent using perpendicular lines.
Exam Revision for Parallel and Perpendicular Lines
In this video we will take a look at exam style questions for perpendicular lines and the equation of a tangent.
