Fórmulas Esenciales de Área y Perímetro

Los cuadriláteros son tus mejores aliados en geometría porque aparecen en todas partes. El cuadrado es el más simple: solo necesitas multiplicar lado por lado A=l2A = l² y su perímetro es 4 veces un lado.

El rectángulo es igual de fácil - multiplicas base por altura para el área A=bhA = b·h. Para el perímetro, sumas dos veces la base más dos veces la altura. Tanto el cuadrado como el rectángulo tienen 360° en sus ángulos internos.

El paralelogramo y el trapecio usan fórmulas parecidas pero con pequeñas diferencias. El paralelogramo usa A = b·h, mientras que el trapecio necesita las dos bases: A = B+bB + bh/2. Para ambos, el perímetro es simplemente sumar todos los lados.

¡Dato clave! El rombo tiene una fórmula especial: A = D·d/2, donde D y d son las diagonales. Es la única figura que no usa base por altura.

Los polígonos regulares como el pentágono (540°) y hexágono (720°) usan la misma fórmula: A = P·a/2, donde P es el perímetro y 'a' es el apotema. Sus ángulos internos aumentan según el número de lados.

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.
