Triángulos Semejantes y el Teorema de Tales

¿Alguna vez te has preguntado cómo los arquitectos calculan alturas de edificios sin subir hasta arriba? La respuesta está en los triángulos semejantes, que son figuras que tienen la misma forma pero diferente tamaño.

El Teorema de Tales es tu mejor aliado aquí. Básicamente dice que cuando tienes triángulos semejantes, sus lados correspondientes mantienen la misma proporción. Por ejemplo: si tienes la ecuación 810=x6\frac{8}{10} = \frac{x}{6}, solo necesitas despejar: x=(8)(6)10=4.8x = \frac{(8)(6)}{10} = 4.8.

El truco de las sombras es genial para medir alturas. Si una persona de 1.8m proyecta una sombra de 0.3m, y un edificio proyecta una sombra de 2m, puedes calcular la altura del edificio: x2=1.80.3\frac{x}{2} = \frac{1.8}{0.3}, entonces x=(2)(1.8)0.3=12x = \frac{(2)(1.8)}{0.3} = 12 metros.

💡 Dato curioso: Los antiguos egipcios ya usaban este método para medir las pirámides. ¡Matemáticas milenarias que sigues usando hoy!

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.
