Mathematical Similarity Summary

To see if two figures are similar, the first ting you look for is to see if they have the same general shape. Figures are mathematically similar if all corresponding angles are congruent. The two images that you are trying to see are similar must also be related by a scale factor. These are two ways that you can see if an image is similar to another one. Another way you can check is by using ratios. You can use true proportions to see if two images are similar.

Any two rectangles are similar

False. Although all corresponding angles are congruent, the sides are different lengths. Not all rectangles can be related by a scale factor, which means they are not similar.

Any two equilateral triangles are similar

True. All corresponding angles are congruent. When the angles are congruent, they are automatically similar.

Good notes and Bad notes

Below is a picture of my good notes. I think these notes are good because thy are correct, neat, and has that line on the side to help edit. I think this is one of my best notes. My goals is for all my notes to be like this. I think the side like really helps me stay neat and organised. I am going to add that for all of my notes.

Above is a picture of some of my bad notes. I think these are bad because they are messy, don’t hold a lot of information, and don’t have the side line thing. I think if I had my side line thing my work would be neater. I also think I need to add more to my notes, there isn’t a lot of information.

Math check In #2

The assignment for the first page was to look at the images, and say which ones are similar and which ones aren’t and why. The way you can tell if an image is similar or not is by seeing if there is a s.f. So that’s what I did, I looked for the s.f and saw which ones had a s.f and which didn’t and that determined if they were similar or not. The assignment for the second page was to look at the images and make a similar and not similar triangle/ rectangle. I did that by making it have a scale factor or not. If it did have a s.f it was similar and if it didn’t it wasn’t. Another way to make sure they are similar or not is by making sure the corresponding side lengths or angles are congruent. Then I made sure my answers fit the requirements!
