Question

A triangle has lengths of 24in 32in, and 40in. Is the triangle acute, obtuse, or right?

Answer 1

All of the angles are less than 90 so what is an angle less than 90 called again? :)

Answer 2

acute?

Answer 3

I presume you know of the Pythagorean theorem?
a2+b2=c2 ⇒ Right Triangle
a2+b2>c2 ⇒ Acute Triangle
a2+b2<c2 ⇒ Obtuse Triangle
There is a special rule for the right triangle though; C must always be the longest side.
I assume you can plug in values and figure out the rest? If not do not be scared to ask me for more help :-).

Answer 4

Correct. It is acute. :)

Answer 5

In general, if c is the largest side and a,b are the other two,
a2+b2<c2⇒obtuse
a2+b2=c2⇒right
a2+b2>c2⇒acute

Answer 6

its acute
