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?2) Describe a way to find a missing side length in a pair of similar figures.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?

1) The Angles have to be the same and the ratias have to be the same
2) you mutiply by 2.5 to get 7.5
3) the side lathes are 6 because 2.5 x 4 = 6

I think you find the similarities if they have the same agels or the scale factor can add into each other exp. (2 sf 4 sf 2 goes into 4).



2. pug is similar to mug because the scale factors can go into each other and the angels are the same. The scale factor is x4. 16 mugs will fit in pug.

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.

2) Compare the angles of the original to the new paper.

3) Compare the area of the new paper to the area of the original.

1) 8 divided by .5 euqles 4 10 devided by .5 equles 5

2) The angles stay the same as the first

2) the new area ofthe small is 40 in 80 divided by.5 is 20
