This learning target addresses writing proofs beyond CPCTC. I originally was confused on the topic and when to use it, but after reviewing our class notes and studying some example proofs I now understand this learning target. The picture below is an example of a proof that goes beyond CPCTC.

This learning target addresses applying the formulas for area and circumference of a circle. I was having trouble remembering the formulas for both area and circumference. So I reviewed the notes we took in class and memorized both the formula. Below is a picture of the notes we took on circles including the formulas for both circumference and area.

This learning target is about identifying medians and altitudes of triangles. When we were taking notes on the subject I had no idea what was going on, but after I went home and did the homework after reading our notes and the book, I understood the concept. Below is the picture of the notes we took in class on medians and altitudes.

This learning target addresses using overlapping triangles in proofs. This learning target isn't specifically a problem for me, it's just that proofs with overlapping triangles are a little more confusing and have more steps. With more practice and doing the homework, I understand the concept. Below is a picture of a more difficult/longer proof from our homework on overlapping triangles.

This learning target addresses applying theorems, relating angle measures and side lengths of triangles. The algebra problems about relationships of angles and sides were the most confusing for me. But by understanding the concept of opposite sides and angles, I am more comfortable with the topic. Below is a picture of a problem from the chapter review where the theorems were needed.

Learning Target #11

This learning target talks about understanding when auxillary lines are used in proofs. This was originally confusing to me because I didn't know when it was necessary to draw them in. After doing the homework and review problems I understand that whenever it is easier (and possible) to use auxillary lines in a proof, they are able to be drawn in. Below is a picture of a diagram with an auxillary line drawn in.

Learning Target #16

This learning target addresses using the RHL postulate to prove right triangles congruent. This was confusing to me because I didn't know the difference between SAS and RHL, but after playing the Kahoot in class and listening to Mrs. Kudlov explain the difference, I am comfortable with the topic. Below is a picture of the notes that we took on the RHL postulate with a practice proof underneath.

Good work. Keep it up. Remember that you should try to use a variety of sources to support your learning: videos, websites, the book and your notes and homework.

Sincerely,

Mrs. Kudlov
