### Pythagoras Scribe Post 5

I did numbers 6,9,12 and 15.

6.
a)
I subtract c² and a² so that i can b².
b)

I first squared the two numbers then subtract them. After that I find the square root of the difference then I got 10cm.

9.Tianna wants to construct a path along the diagonal of her yard.What length will the path be?Express your answer to the nearest tenth of a metre.

12.The hypotenuse of the triangle cuts the circle in half.What is the diameter of the circle? express your answer to the nearest tenth of a centimetre.

Here is a video to help.

I'm not sure about my answer in no.15 but I think i'm wrong.

1. Great job Karen! I liked how you color, pictures, links, and videos. Your scribe was also neat & organized, great job!
- #15
The answer to number 15 is 4.47, or 4.5 because the line segment A & B starts from point 2, and ends at 6. The distance between 2 & 6 is 4. Instead, you started from point 0. So instead of putting 6x6, it should be 4x4, but nice try! :)

2. Great job Karen! Your scribe was very understandable, neat, organized and colorful (: and I agree with Marilen!

3. GREAT JOB KAREN! I liked the way you included a video, links, and pictures. Also, your scribe was understandable. Next time, only use colors for important words or numbers because your scribe would look like a bag of skittles :) Anyways, keep up the good work!

4. Great job, Karen! I liked how your scribe was easy to understand, and you included everything. It's nice how you tried number 15, even if you weren't sure of your answer! Next time, try not to add so many colours. Overall, you did great. :)

5. Good Job Karen =) I liked how you post had everything. As in, videos, links, pictures and colour! Keep up the great work!
