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.

  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.

  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.
