Teorema de Pitágoras e seus elementos

O Teorema de Pitágoras relaciona os lados de um triângulo retângulo através de uma equação simples mas poderosa. Em palavras simples: o quadrado da hipotenusa é igual à soma dos quadrados dos catetos.

A hipotenusa é o maior lado do triângulo retângulo e fica oposta ao ângulo reto (90°). Já os outros dois lados são os catetos - aquelas partes que formam o famoso ângulo de 90° entre si.

O cateto adjacente é aquele que fica ao lado de um determinado ângulo (sem ser a hipotenusa), enquanto o cateto oposto é o que fica na frente do ângulo que estamos analisando.

Dica prática: Para lembrar facilmente a fórmula, pense que: c² = a² + b², onde c é a hipotenusa e a e b são os catetos. Essa fórmula é sua melhor amiga para resolver exercícios com triângulos retângulos!

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.
