Answer 1

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

Answer 2

Try pythagorean theorem. It will only work for right triangles (and in this case, it does)

Answer 3

Acute: all angles less than 90

Answer 4

Um thats not how this works...

Answer 5

Hi!

Answer 6

._.

Answer 7

Wouldn't you be able to justify it that way? Guess not

Answer 8

Do you mean my definition of an acute triangle is wrong? Is there a different one? I'm confused...

Answer 9

You can lol i know using that will help however im kinda confused on how to tell if its acute or obtuse the signs....

Answer 10

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.

Answer 13

Guys i dont think you understand the question...

Answer 14

Answer 15

@CShrix you had the right idea justify it with using the Pythagorean theorem

Answer 16

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
