Answer:
1. The Pythagorean Theorem is a relationship between the lengths of a right triangle.
2. a^2 + b^2 = c^2 C. 35.6
3. No, Seraphina is not correct because the sum of the square of both sides does not equal the hypotenuse squared.
4. I would divide the triangle through the middle to make it into 2 right triangles. So you would get 25.4 units which rounds to 25 units.
