Fórmulas Esenciales de Geometría

Las figuras planas son tu punto de partida en geometría. El cuadrado tiene área A = l·l (lado por lado), mientras que el rectángulo usa A = b·h (base por altura). Para el triángulo, recuerda la fórmula A = b·h/2 - es la mitad del rectángulo que lo contiene.

El rombo funciona diferente: A = D·d/2 (diagonal mayor por diagonal menor, dividido entre 2). El trapecio suma las dos bases: A = b+Bb+B·h/2. No confundas el romboide con el rombo - el romboide usa A = b·h como el rectángulo.

Para el círculo, necesitas dos fórmulas clave: área A = πr² y perímetro P = 2πr. La diferencia entre área y perímetro es fundamental - una mide la superficie, la otra el contorno.

¡Truco! Dibuja cada figura mientras memorizas su fórmula - tu cerebro recordará mejor con imágenes.

Los polígonos regulares tienen fórmulas especiales que aprenderás según avances en el curso. Lo importante es dominar primero estas figuras básicas.

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.
