Okay, so how do i determine if a couple of sides will form a right triangle? well, here i can use the converse.
00:07
What's the converse? kind of like if i switch the if and then of statement.
00:11
Converse of the pythagorean theorem.
00:14
So the pythagorean theorem says, if i have a right triangle, then a squared plus b squared equals c squared.
00:22
The converse says, if a squared plus b squared equals c squared, then they form a right triangle.
00:29
So what i'm going to do, if i have 15, 36, 39, okay, what's a, what's b, what's c? a and b doesn't matter, but c is always the longest side.
00:43
So c will have to be 39.
00:44
So i'm going to do 15 squared plus 36 squared equals 39 squared.
00:48
See if this works out.
00:50
15 squared is 225.
00:52
What's 36 squared? 36 squared is 1296...
