Pythagorean Relationship

1. The Pythagorean relationship is when the sum of the area of the two squares attached to the triangle's leg equal the area of the square attached to the triangle's hypotenuse. (a²+b²=c²)

Question 2

Question 3

No, it's not a right triangle. As you can see, I did my calculations on the paper. I say this isn't a right triangle because in my calculations, the sum of the area of the squares attached to the legs is 100 cm² (which is 10 cm in length). However, on the image, it says that the hypotenuse is 11 cm in length and has an area of 121 cm². This doesn't follow the formula of the Pythagorean relationship which is a²+b²=c². In short, the sum of the area of the squares attached to the legs don't equal the area of the square attached to the hypotenuse.

6. Josh, you post is AWESOME! I liked how your pictures were clear and easy to see, and the way you had two videos and two links. One tiny problem you have is the T-chart, you forgot to put the degree symbol after 90 in the square column. You can also link to or mention the game "Sigma Prime" in mangahigh which is a game about Factorization. Great Job Josh!
