Is there any way on how to do Pythagorean theorem easier im having trouble understanding

Honestly, it isnt that bad. You will get used to it after practice.

i wonder how we figured out the pythagoream theorem

It was proven by Pythagoras. There are several popular proofs (even one done by a former US president [Garfield]). Look up proof of Pythagoras Theorem on YouTube.

Just a quick question, so in a test it could say find the distance of the other 2 sides of the triangle. Can you find out the other 2 sides using the pythagorean theorem or is there another way to find that out?

There is no way to do it if you are only given 1 side :(

Hey Jordan! Here's the process: a² + b² = c². C is the hypotenuse or the longest side of a triangle. B and A are the adjacent and opposite sides. To solve for the unknown side, just substitute the variables with the given numbers, then solve what's necessary, and you will get your answer! here is an example: a = 5, b - x (unknown side), and c = 10. Step 1 (write it out): 5² + x² = 10². Step 2 (solve the squares): 25 x² = 100. Step 3 (necessary solving): 1 - subtaract 25 from both sides: x² = 75. Now you have your answer: x = √75. Hope this helped!

how can i find the b (the one one the side thats straight)

you would instead do c^2-a^2=b^2. if you are missing "a" you can also swap those and do c^2 - b^2 = a^2

So, for the Pythagorean Theorem you do a squared plus b squared equals c squared. Why is a+c=b a thing? I don't get it.

a+c cannot equal b. This is because c is the hypotenuse. Instead, you could do c²-a²=b².

Practice using the Pythagorean theorem to solve for missing side lengths on right triangles. Each question is slightly more challenging than the previous.

Pythagorean theorem

The equation for the Pythagorean theorem is

a, squared, plus, b, squared, equals, c, squared

where a and b are the lengths of the two legs of the triangle, and c is the length of the hypotenuse.

[How can I tell which side is the hypotenuse?]
