Summary
Various geometric principles relating to triangles, quadrilaterals, and
circles are important to learn. Many of these principles are applied to obtain
needed data for calculating tool locations. There are several propositions
relating to angles that should be learned by an individual applying math to
calculate tool location.
Using trigonometry to solve for the various parts of a triangle is
an important concept. Tool location is often determined by using the
trigonometric functions. There are six trigonometric functions and each
is defined relative to the relationships between two sides of the right
triangle.
