Math

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.
The new side lenghts of of the reduced figure is 5 by 4.


2) Compare the angles of the original to the new paper.
The angle are corresponding the never change.



3) Compare the area of the new paper to the area of the original.
The original area is 80.
The new area is 20.
The original area is 4 times bigger then th new area.
