Also, there is a review of the important vocabulary below. If you haven't made your flashcards yet, get them done! :)
Today we learned about the angles on the outside of the triangle, which are called exterior angles. We also learned that each exterior angle has two remote interior angles, which are the angles inside of the triangle that are far away from the exterior angle. Imagine you are sitting on the exterior angle; you would need a remote to change a TV in the remote interior angles because they are just too far away. :) Also, there is a review of the important vocabulary below. If you haven't made your flashcards yet, get them done! :) Today we talked about the angles in a triangle. We learned that all the angles in a triangle add up to 180*. We used a lot of our algebra skills today, too! Check out the notes below, and the videos from class if you'd like, then get your homework done!
Today we started topic 11, which focuses on Geometric Reasoning. Today's lesson was all about angle relationships. We reviewed some angle relationships that we learned about in 7th grade, and we learned about some new relationships too. These videos are a great review of everything we discussed in class today. Notes from today are also in the slide show below.
Today we talked about similar triangles. Remember from Topic 10 that two figures are similar if they are the same shape but different sizes. We can use our knowledge of angles to prove that two triangles are similar. Triangles are similar IF they have two pairs of congruent angles. Sometimes we have to use our other angle knowledge to help us figure out if angles are congruent. Take a look at our notes in the slideshow below. Remember to catch up on topic 11 homework, including tonight's 11-5 homework. You have a vocabulary test on Friday, and the topic 11 test on Monday. |
