Which best explains whether a triangle with side lengths 2 in., 5 in., and 4 in. is an acute triangle? the triangle is acute because 22 + 52 > 42. the triangle is acute because 2 + 4 > 5. the triangle is not acute because 22 + 42 < 52. the triangle is not acute because 22 < 42 + 52.

Let

we know that

If -----> is a right triangle

If -----> is an obtuse triangle

so

substitute the values

------> is an obtuse triangle

therefore
