Classify the triangle based on the side lengths 9, 40 and 41.
What's a triangle called if it has all sides unequal?
no triangle can be formed with given side lengths, maybe? or its OBtuse?
Plus, you may see if it is right, obtuse or acute with their respective formulas.
you can form a triangle here
\(a^2 + b^2 = c^2\) Right ^ \(a^2 + b^2 > c^2\) Acute ^ \(a^2 + b^2 < c^2\) Obtuse ^ c is the longest side.
so the only answer is Acute, because its all angles are less than 90?
you're not given angles
They are the sides.
You compare \(9^2 + 40^2\) and \(41^2\) and check what's greater.
so its A, since B, C, D are given angels?
Umm. I think you are confused here. Just compare \(9^2 + 40^2\) and \(41^2\).
Yes I am..
What's \(9^2 + 40^2\)?
81+1600= 1681
Correct. Now what's \(41^2\)?
woah.. same asnwer... so its a RIGHT triangle? B?
Yes.
