Math Reflections Investigation #4

Answer the following questions on YOUR blog as a post. Use the same title as mine for your post. Write your answers in complete sentences! An easy way to do this is to copy and paste the questions below onto your post and then put your answers in a different color!
1) What has to be the same in order for two parallelograms to be similar?
For a parallelogram to be the same you have to have the same angles and ratio.

2) Describe a way to find a missing side length in a pair of similar figures.
Find the scale factor from one figure to another.

3) I have a small isosceles triangle with a base of 3 inches and other sides are 4 inches.I want to create a similar isosceles triangle with a base of 7.5 inches.What should the other side lengths be and why?
the other sides should be 10 because to get from a to be you have to do 3 times 2.50 and you get 7.5 so 4 time 2.50 is 10

For this 10 point assignment - answer the following questions in COMPLETE sentences and use examples to help support your answer. You could copy and paste these questions onto your blog if you need to and then type your answers in different colors. Write me a comment on this assignment when you finish! :)
1) Think back to Mug Wump - how did you decide which characters were similar to him? How did you decided which characters were NOT similar to him? Same angles and non same angles


3) If I used (x, y) to create Mug and I used (4x, 4y) to create a new character, Pug, how would Pug be similar to Mug? What is the scale factor from Mug to Pug? How many Mugs would fit into one Pug (area)? It would be similar by having the same angles and doubles sides. 4 mugs would fit into one pug.

I like the idea of blogging in school

Sometimes when I make copies of worksheets for you, I reduce the the original to waste less paper! (one small thing to help save our planet! :) http://www.ourearth.org/Let's say that my original paper is 8 inches by 10 inches. I type in 50% to the copier to reduce the paper. Using the math reflection rubric I handed out this year, answer the following questions on your blog (1 bonus point for answering in paragraph form instead of question/answer form):

1) Compare the oringinal paper's side lengths to the new paper's side lengths.
8 divided by 2 =4 10 divided by 2 =5 so it would be 4 by 5
2) Compare the angles of the original to the new paper.
the angles would be the same
3) Compare the area of the new paper to the area of the original.
the length is reduced by 2 times

I think we did this to talk to other people about math.
We also did this to learn more from other people.
the point is to make school fun and enjoyable
