## Geometry

Geometry is one of the most important math courses. Geometry introduces many key formulas and topics that will later be used in more advanced math courses. Geometry is usually taken as s sophomore however many freshman take geometry as an advance course. Geometry introduces many things including lines, angles, trigonometry, polygons,triangles, quadrilaterals, circles, area, volume, surface area, and many more. These theorems and formulas are build upon basic math principles.

Geometry courses usually take the student through many objectives and learning. Geometry builds upon the basic principles of math you have already learned. Geometry usually entails trigonometry as well which is them taken the next year.

One of the beginning formulas for trigonometry is used to find a side or angle of a triangle. The formula uses sine, cosine, and tangent. The formula used is S o/h C a/h T o/a. The S stands for sine, C for Cosine, T for tangent. In order to use this formula you must know at least one side and solve for the unknown side. The o stands for opposite side, the a stands for adjacent side, and the h stands for hypotenuse. You can also use inverse trig to solve for an angle if you know the sides lengths.

There are many theorems and postulates in geometry. These theorems and postulates prove simple and complicated principles of math. A example of one is: If two parallel lines are cut by a transversal, then each pair of corresponding angles is congruent. This is one of the easier postulates.
