Answer:
To find the pythargoeren(sorry I do not know how to spell this word at all:) you can use the formula a^2+b^2=c^2.
Explanation:
If you recieve the numbers for the longest side and a shorter side then here is how you would set it up: 7^2+b^2=12^2 that was an example.
And if you recieve the numbers for the two shortest sides the set it up like this: 7^2+4^2=c^2
Just so you know these are for example and I am not actually sure if they equal a right triangle or if they are true
Good luck.
