# 3 DIMENSIONAL PYTHAGOREAN THEOREM

Pythagoras Theorem in 3D - MATH
You can read more about it at Pythagoras' Theorem, but here we see how it can be extended into 3 Dimensions. In 3D. Let's say we want the distance from the bottom-most left front corner to the top-most right back corner of this cuboid: First let's just do the triangle on the bottom. Pythagoras tells us that c = √(x 2 + y 2)

Pythagoras' Theorem in Three Dimensions
A three-dimensional object can be described by three measurements - length, width and height. We can use Pythagoras' Theoremto find the length of the longest straw that will fit inside the box or cylinder.

How to prove the Pythagorean theorem in three dimensions
Apparently, the “three-dimensional Pythagorean theorem” is called de Gua’s theorem [ 1]. It says that if we have a tetrahedron A B C D where angles B A C, B A D and C A D are all right angles, then the square of the area of triangle B C D is the sum of the squares of the areas of triangles A

While Euclid's proof only applied to convex polygons, the theorem also applies to concave polygons and even to similar figures that have curved boundaries (but still with part of a figure's boundary being the side of the original triangle). The basic idea behind this generalization is that the area of a plane figure is proportional to the square of any linear dimension, and in particular is proportional to the square of the length of any side. Thus, if similar figures with areas A, B and C are erected on sides with corresponding lengths a, b and c then: $${\displaystyle {\frac {A}{a^{2}}}={\frac {B}{b^{2}}}={\frac {C}{c^{2}}}\,,}$$ $${\displaystyle \Rightarrow A+B={\frac {a^{2}}{c^{2}}}C+{\frac {b^{2}}{c^{2}}}C\,.}$$But, by the Pythagorean theorem, a + b = c , so A + B = C. Conversely, if we can prove that A + B = C for three similar figures without using the Pythagorean theorem, then we can work backwards to construct a proof of the theorem. For example, the starting center triangle can be replicated and used as a triangle C on its hypotenuse, and two similar right triangWikipedia · Text under CC-BY-SA license

The Pythagorean Theorem states that the sum of the squared sides of a right triangle equals the length of the hypotenuse squared. You might recognize this theorem in the form of the Pythagorean equation: a 2 + b 2 = c 2
