In this lesson I will be teaching you about other angle relationships in circles. These “other angle relationships” I’m talking about are those angles formed that are not inscribed angles. Of course I assume you watched the lesson on inscribed angles if not please watch it before this lesson. Ok these other angles are formed by two chords or sometime tangents and chords that cut through a circle. As you will see in the video there are quite a few different ways we can form these angles. As with inscribed angles we will be looking at these other angles in terms of angles and arc measure. Many students find the formulas a little confusing so you need to really focus and make sure you are using the correct formula for the problem you trying to solve. It should come as no surprise that we will be using algebra to help us solve these problems so review algebra as much as you can especially equation solving. How are your notes? complete, neat and organized? I can tell you from many years of teaching that top students almost always have great notes- keep developing excellent study habits the investment will pay off big.
