Using the notion of similar triangles he was ready to calculate the peak of pyramids by comparing the dimensions of their shadows with scaled-down, very similar triangles of known dimensions. Likewise he calculated the distance to ships at sea by noting the azimuth angle with the ship from the baseline of two commonly spaced observation details a known distance aside about the shore and scaling up the distance towards the ship from the scale of the lesser related triangle.
