Week 17

Class went well. We took our very first formula madness quiz. We will take another one next week. There is nothing new to add to our formula madness. But I might change some of the letters in the quiz. So make sure that when they memorize the formulas for the proportions or the geometric mean they understand how to do it with different variables, because the variables will change. Formulas for area variables will not change. After the quiz we went over in detail the different answers and what options they have to write them down so that they were clear on the expectations. We cover three sections 7.4, 7.5, and 7.6. In 7.4 we covered similar triangles. This was an extension of a similar polygons that we did last week. On the section 7.5 we had proofs. I went over three proofs with them which are extremely similar to the ones they’re going to have for their homework. You can watch the videos on them to make their homework more clear. On section 7.6 there were some more ways that triangles form proportions. If you have any questions please send me the section number and problem number and I can make a video for you. It is likely that if one person has a question on a problem then someone else does too.
