Question

Classify the triangle with side lengths of 24, 18 and 30 as acute, right, or obtuse.

Acute
Right
Obtuse
Not a Triangle​

Answer 1

Answer: Choice B) Right

Step-by-step explanation:

We have a triangle with sides of:

• a = 18
• b = 24
• c = 30

Plug those values into the pythagorean theorem equation.

a^2+b^2 = c^2

18^2+24^2 = 30^2

324+576 = 900

900 = 900

We get a true equation, so this triangle is a right triangle.
