I know how to do the problem I just forgot how to tell if they are acute obtuse or right i know if the numbers are equal (same) its right i cant tell the difference between obtuse and acute
Try pythagorean theorem. It will only work for right triangles (and in this case, it does)
Acute: all angles less than 90
Um thats not how this works...
Wouldn't you be able to justify it that way? Guess not
Do you mean my definition of an acute triangle is wrong? Is there a different one? I'm confused...
You can lol i know using that will help however im kinda confused on how to tell if its acute or obtuse the signs....
An acute triangle is a triangle with 3 angles that are all less than 90 degrees. An acute triangle has 3 acute angles. A right triangle is a triangle with 2 angles that are acute angles, and one angles that is 90 degrees. An obtuse triangle is a triangle with 2 angles that are acute, and one angle that is more than 90 degrees. An angle more than 90 degrees is an obtuse angle.
Okay, I thought I was going crazy X)
^ That's what I was trying to say.
Guys i dont think you understand the question...
@CShrix you had the right idea justify it with using the Pythagorean theorem
a^2+b^2=c^2 plugin numbers if you get equal sides then it's right triangle if \[c^2< a^2+b^2\] then actue if c^2>a^2+b^2 then obtuse
^ thats what i was looking for nnesha thanks :) And thanks to all who helped =)
Oh, I get it.
nn u r great :)
I get confused on that part :P
@TheSmartOne i apologize for not medaling u but you've been fanned.
remember c= longest side
Perfect :D thanks @Directrix and @Nnesha :D And that really helps c:

How does 52^2 compare with the sum of 20^2 and 48^2 ?
