Study Notes
Trigonometry is a branch of mathematics that deals with angles in triangles and other shapes. It's concerned with relationships between different parts of these figures, like their sides, lengths, and areas. One important concept in trigonometry is the angle that has been measured within a triangle. This can also refer to angles outside of triangles. Angles measure how much one side of a shape turns around another side when you trace along it from its starting point back to where you started. For example, if two lines meet at a point, they form an angle where one line turns around the other one. If those two lines were straight, this would just be called a right angle; otherwise, the sum of all three angles would equal (180^\circ).
In order to understand more complex ideas in trigonometry, mathematicians use basic geometric concepts such as perpendicularity, parallelism, similarity, equivalence, congruency, and symmetry. These become extremely useful because once we have them defined by Euclidean geometry, we don't need any further definitions within our system—we only need definitions of operations on things already well defined within geometry itself.
One of the most common uses of trigonometric functions is finding distances in space. Given two points A(x1, y1) and B(x2, y2), the distance dab equals (\sqrt{((x2 - x1)^2 + (y2 - y1)^2)}). In general, trigonometry allows us to connect various mathematical objects together through the properties of angles and ratios between them. We can use it to solve problems involving circles, squares, rectangles, parallelograms, and many other types of polygons. When combined with algebraic equations, trigonometry provides powerful tools for solving geometric problems.
