Question

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

Answer 1

It's a right triangle

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

Answer 2

It is a Right Triangle.

Explanation:

30^2 = 900

24^2 = 576

18^2 = 324

576 + 324 = 900

This satisfies the Pythagoras theorem so it is a Right Triangle.
