A Level Maths: Straight Line Geometry
The Question
Starting the question
In this article we are going to explore how to solve the above question which relates to straight line geometry.
With questions like this it is important to take note of important keywords within the question and in this case it is the work perpendicular.
Remember that for two perpendicular lines:
Making a start
To start you can find the gradient of the line AB
We are asked to find the value of c, and this can be done by finding the equation of the line BC.
Using:
As a question this is not overly difficult but the key is to understand what the question is asking and identifying the keyphrases within the question.
As you embark on your A Level Maths journey you are going to come across a lot of questions and a lot of terms. It is these terms that you need to know and to be able to translate them successfully into the appropriate technique in mathematics.
Half term A Level Maths Revision Courses can certainly be a help with this. They are intense and there is a lot of work to be covered within 3 or 4 days.
As with any maths question, the aim is to keep solutions clear and if using a diagram which is especially so with geometry, make it big and clear.
Good Luck!
