Using the side lengths determine whether the triangle is acute obtuse or right 24 30 18

Step-by-step explanation:

For a ≤ b ≤ c:

if a² + b² = c², then a triangle is a right triangle

if a² + b² < c², then a triangle is an obtuse triangle

if a² + b² > c², then a triangle is an acute triangle.

We have a = 18, b = 24, c = 30. Substitute:

18² + 24² = 324 + 576 = 900

30² = 900

18² + 24² = 30² → a² + b² = c²
