Coordinate Geometry Tips For Exam Questions

Coordinate Geometry Tips for Exam Questions

Have you ever looked at a maths exam question and felt so confused, like it was written in a secret code you could not understand? These new spec, tough coordinate geometry and graph questions can leave students feeling confused, so here are a few tips on how to tackle them!

Mathematical skills we need:

o How to find a midpoint

o How to find a gradient with two coordinates

o How to rearrange into the form y = mx + c

o How to find the equation of the line from a gradient and one coordinate

o How to tell if lines are parallel or perpendicular

o Properties of quadrilaterals

o Finding points of intersection by equating equations of lines

o Circle Theorems

o Sharing ratio

Key Tips to tackle questions like this

o Draw a diagram

o Label whatever information you have

o Mark what we are trying to find

o What information do we need to work this out?

o Step by step, what info can you deduce from each line.

To ensure you get marks on these questions

o Can you work out a gradient?

o Any perpendicular gradients?

o Can you find any missing coordinates?

o Draw a diagram

o Rearrange equations into y = mx + c
