The answer, although interesting, is about angels, not angles which is what the question was about!

Geometry has its roots in ancient people trying to measure plots of land which were flooded annually by the Nile. When the flood waters receded, land had to be restored to its former owners and it was important to know how much land each landowner had before the flooding. The likelihood that taxes were partly based on the area of land owned made it particularly important to get the calculations right. The areas of some shapes are relatively simple to calculate from the lengths of their sides but for some shapes it is easier if angles (and their trigonometric ratios) can be used in the calculations.
