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) in order for 2 parallelograms similar they both must have a similar scale factor for the side lenghts. Another way you will know two parallelograms are similar by looking at the angles. If both parallelograms have the same angles and the SF inorder to be the same
2) One way you can find a missing side length from a pair of similar figures is by deviding two similar side lengths that both figure have in common. So if the figures have atleast one ajescent devide both of those numbers do get a number then multiply the other side by the number that you got from deviding the last 2 numbers and you will get the other missing side length on the figure
1) the missing side lengths would be both 10 because

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?
2) 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)?
1) Back to the Mug Whump if you wanted to decide if the figures were similar to each other the numbers could have been devided or multiplied into the other numbers evenly. If the numbers couldnt be devided or multiplied into the other figures numbers evenly then the firgure was not similar in any way.
2) If you were to do (4x,4y) to create Pug frommug then Pug would be exactly 4 times larger then Mug. The scale facter from Mug to Pug would be the length would be 4 times larger than Mugs and Pugs hight would be 4 times larger than Mugs. If Mug were to fit into Pug then Mug could fit into Pug 16 times.

This is for a summative grade worth 12 points (3 points each question).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)The reduced side length are half of the original
2) The agnle measures stay the same
3) The original is 4 times larger
1)The reduced side length are half of the original
2) The agnle measures stay the same
3) The original is 4 times larger
