As with triangles and other polygons, quadrilaterals have special properties and can be classified by characteristics of their angles and sides. Understanding the properties of different quadrilaterals can help you in solving problems that involve this type of polygon.

This section provides the fundamental building blocks for working with the most basic quantity in Trigonometry - the angle. We delve into as much detail about angles as we dare, without introducing unnecessary topics. We cover a little bit of required Geometry for success in Trigonometry, and wrap things up with a brief geometric review of circles (another foundational topic for Trigonometry).

A line segment that passes through a circle’s center connecting two points on the circle is called a diameter. The diameter is twice as long as the radius. The size of a circle can be measured in two ways. The distance around a circle is called its circumference. Archimedes discovered that for circles of all different sizes, dividing the circumference by the diameter always gives the same number.

If a and b are the lengths of the legs of a right triangle and c is the length of the hypotenuse, then the sum of the squares of the lengths of the legs is equal to the square of the length of the hypotenuse.

It covers conversions from rectangular to polar coordinates, area and volume calculations under various geometric shapes (like cones and spheres), and the properties of radial functions. Key topics include evaluating integrals, calculating areas and volumes, and understanding joint density functions associated with normal distributions.
