LC - Coordinate Geometry
LIne
The booklet to the right is OL material, it is however a good start for HL students looking to recap JC HL topics. It does however have one new type of questions, Area of Triangle.

Distance Formula
|
A nice short video on how to use the distance formula.
It also shows how to plot points on a plane if you watch the opening closely. If you're interested!! The distance formula is just a version of Pythagoras Theorem. |

Circle
Some practice questions, probably best to wait till the end of the section to attempt these. They have a bit of everything in them!

Syllabus Context
Geometry combines with Trigonometry to make up strand number 2 of the Leaving Certificate Project Maths. The below listed learning outcomes are broken into three parts, it should be remembered that trigonometry is very easily mixed with Geometry especially for exam questions. Coordinate Geometry
