For 3D Pythagoras, there is a new equation we can use, which just uses Pythagoras’ theorem twice. We think that one reason for this is that the new questions types on the major GCSE Maths exam boards such as AQA, OCR and Edexcel, all look to have more application and context within them and 3D questions can offer this. The Corbettmaths video tutorial on 3D Pythagoras. AY =\sqrt{81+36+36}=\sqrt{153}=3\sqrt{17} cm. Here we use 3D Pythagoras to find that AY is. Now we make another triangle with its base along the "√(x2 + y2)" side of the previous triangle, and going up to the far corner: We can use Pythagoras again, but this time the two sides are √(x2 + y2) and z, and we get this formula: So it is all part of a pattern that extends onwards: So next time you need an n-dimensional distance you will know how to calculate it.

It is called "Pythagoras' Theorem" and can be written in one short equation: And when we want to know the distance "c" we take the square root: You can read more about it at Pythagoras' Theorem, but here we see how it can be extended into 3 Dimensions. 3D Pythagoras (Maths Genie) 3D Trigonometry Although 3D trigonometry questions seem daunting, they can usually be broken up into a series of small steps, which help you to visualise your problem. In 3D. 3d trigonometry and PythagorasUsing Pythagoras to find sides in a pyramidEssential Grade 8 GCSE Maths revision videos Therefore, the distance from the centre of the base to C is 5\sqrt{2}. Calculate the perpendicular height of the pyramid. If we draw a line from the apex at E down to the centre of the base, then that line represents the perpendicular height, since we know the apex is directly above the centre. First of all, we can work out the length of DB by Pythagoras or by recognizing that the diagonal of a square is \sqrt{2} \times \text{ side length}, thus: Hence the length from D to the centre of the square, O, is half this value. First what we need to do is find FH, this will give us the base of the right-angled triangle FHC, which will let us find FC.
