More on Angles and Lines

In this lesson I will be teaching you more about angles and lines.  I can’t stress how important it is for you to master and understand all the various properties about angles and lines as we will be using them a lot in geometry.  Some of the things we will be studying in the lesson are complementary and supplementary angles as well as vertical angles.  Complementary and supplementary angles are those angles that are formed with respect to 90 and 180 degree lines- you will see this clearly in the lesson.  Vertical angles are those angles formed when two lines intersect.  Like I was saying the building blocks of geometry are angles and lines- so as you can imagine there is a lot of properties, theorems and postulates to learn.  Please take excellent notes and practice is a must if you really want to master the concepts.
