Pythagorean Theorem

Também conhecido como: Pythagoras Formula, Right Triangle Formula

a^2 + b^2 = c^2

a² + b² = c²

O que calcula

In a right triangle, the square of the hypotenuse equals the sum of the squares of the other two sides.

variáveis

Símbolo	Nome	Unidade	Descrição
a	Side a	—	One leg of the right triangle
b	Side b	—	Other leg of the right triangle
c	Hypotenuse	—	The longest side, opposite the right angle

Derivação

Can be proven geometrically: arrange four copies of the right triangle into a large square. The inner square has side c, and its area c² equals the large square area minus the four triangle areas.

Exemplos trabalhados

1c² = 3² + 4² = 9 + 16 = 25

2c = √25 = 5

Resultado: c = 5
