any three numbers can represent the sides of a triangle
if you don't include conditions on the angles.
Hello. I was wondering how do you find out how numbers can represent the lengths of the sides of a triangle that has a square root and just numbers.
An example would be this one: 7, √5, 3√6. would this be an obtuse triangle?
Also would anyone care to explain? Thanks.
Is it a right, acute, or obtuse?
You can, but the explanation requires trig to find out.
The cosine rule says that and so
Where are sides and are angles opposite sides respectively
