“How can we measure real world triangles accurately?”


In surveying, it is often useful to measure triangular areas. However, how exactly is this accomplished? Well, let’s use our engineering mindset to find out. We know from high school trigonometry that if we can find the length and angle of one side of a triangle then we can find out the rest with ease. So how what if we were to apply this idea in reality successive lengths of rods whose length were accurately known? Well, this is the fundamental idea behind surveying triangulation and was the main surveying technique before the 1950s
