Which one is a right triangle and not a right triangle

15, 8, 17

Step-by-step explanation:

In order to be a right triangle, the side lengths must satisfy Pythagorean Theorem: a² + b² = c² ; where a and b are the legs (smallest side lengths) and c is the hypotenuse (largest side length).

Let's try 10, 11, 15:

10² + 11² = 15²

100 + 121 = 225

      221   = 225

 FALSE → not a right triangle

Let's try 15, 8, 17:

15² + 8² = 17²

225 + 64 = 289

      289   = 289

 TRUE → is a right triangle!

if i remember correctly with perpendicular stuff you just take away the negative

this is a very good question

i got a hair cut today from my mom not to flex just to flex kim jon un is one rad fellow i'd say you'd need to take the hairline in kinda like a box shape like someone rammed a lego brick into your head. from there you really need to take the top up keeping with that boxy aesthetic, finally coat the whole thing with gel if your country economics are failing or whatever you can just coat it with the starving children's food rations. about 5 orphans per strand is a good ratio. good luck with the fresh cut my dude
