Pythagoras Method Tips for GCSE Maths
LikeAre you a maths student who is struggling with the Pythagoras´ Method? This theorem is one of the key theorems learned during GCSE maths and can often feel quite difficult to start with. However, once we´ve mastered it, it can be enjoyble and satisfying to solve problems using Pythagoras´ Theorem. If you still need to get to this point, here are some tips to perfect the method for your GCSE Maths classes and to help your performance with your maths tutor.
A question students often ask is, "when will I actually use this theorem in everyday life?" The truth is, you might not need to, but you may find someday that the theorem comes in very useful and you´ll be thanful for the time you spent learning it. Maybe you´ll go into civil or structural engineering, meaning you may need to rely on this theorem often. Alternatively, you could be a home-owner and want to build a ramp to enter your home. Here´s where Pythagoras´ Theorem can come in again, as it can help you calculate the height that the ramp needs to be. Whatever the need, you´ll never really know when this theorem could come in handy.
Pythagoras Method Tips
a^2 + b^2 = c^2
"a squared +b squared = c squared"
Tip one:
The Pythagoras Theorem is only to be used for right angles triangle's, to find a missing side length.
Tip two:
The side labelled 'c' has to be the hypotenuse. This is the longest side of the triangle, which is the side opposite the right angle.
When finding c, the other two sides can be either a or b.
Tip three:
To find the length of side ‘a’ or ‘b’, you need to label your unknown as ‘a’ and use:
a squared = c squared – b squared
Tip four:
To avoid rounding errors, do not round your figures until the very end value is achieved.
Tip five:
You can use Pythagoras Theorem when only one side length is unknown.
If you have 1 side length and an angle (other than the right angle), then you will need to use Trigonometry.
You can find great videos of Pythagoras Theorem online at Maths Made Easy, Maths Genie, YouTube Khan Academy and in your revision guides provided by your school.
Referring to the longest side of a right-angled triangle as the ‘hypotenuse’ will also help with your trigonometry studies.
Pythagoras Theorem is a grade 4/5 concept. 3D Pythagoras is generally grade 7. It makes a regular appearance on the GCSE Exam.
