WILL GIVE BRAINLIEST (someone help me with this pythagorean theorem) im in 8th grade and just started this and im confused ;c
plzzzzz

Answer:
Step-by-step explanation:
For #1. The equation is a^2 + b^2 = c^2. If it’s a right triangle. Both sides will equal out. A and B are sides, and C is the slanted side (hypotenuse) so you’d do
13^2 + 84^2 = 85^2
169 + 7056 = 7225
7225= 7225
hope that helps you figure out the rest.
Answer:
the sum of the squared sides of a right triangle equals the length of the hypotenuse (the longer side) squared.
so square both sides and add them then square the longer side and if they equal each other it is a right triangle.
