### Right Triangles and Pythagorean Theorem

1) Explain a²+b²=c²

a²+b²=c²
4²+3²=c²
16+9=c²
25=c²
In this triangle, a²=4 cm², b²=3cm². To figure out the hypotenuse you use the formula a²+b²=c². After you figure out what c² equals (25), you find the square root.√25 = 5. So the hypotenuse is 5.
2) Use a second grid to create a²+b²=c²
3) Make the triangle c² to c... How?
To make the triangle c² to c you find the square root of the answer for c².

This is another link to a website with math games.

1. Good Job Hazel! I liked your boarders.. They look cool. I liked how you changed the font colours when it's an important word. The links weren't that bad. And I liked how you posted two videos.

2. Great job Hazel! I really like the pictures you made, it was made very clearly and easy to understand! The first video helped a lot! I like how you only changed the font color of the important words! Keep it up!

3. Awesome job Hazel, I like how you change colors and how you made the font size bigger. Your pictures are nice they are well done. I also like how you put 2 videos, that helped a lot. I loved the link that your posted, especially the one with math games. Keep ut the great work.

4. Well done. This is a great post.

5. Good job hazel! It is really organized and easy to understand. The videos are really helpful. You have nice pictures. But Next time you should add more colors

6. You did a very goob job creating the post. The pictures looked nice and the touches of colour to the important words were very good. However, the title should be 'Right Triangles and *the* Pythagorean Theorem' to make it sound better. Great job again.

7. Good Job Hazel! I like how you only changed the color of the font for the important words, i also like the videos you put. Good Job!

8. Nice post Hazel! I like the videos and links you put, they were very helpful. I also like the pictures you put. Good job!

9. Good post Hazel. I really liked the pictures and how organized the post was. I can't see any thing wrong with it it was a good post.
