Question

Which math sentence can be used to determine if this triangle is a right triangle? A triangle has side lengths 12, 15, 18. 12 + 15 = 18 12 squared + 15 squared = 18 squared 12 + 18 = 15 12 squared + 18 squared = 15 squared

Answer 1

b

Explanation:

Answer 2

12^2 + 15^2 = 18^2

Explanation:

If we have 3 sides of a triangle we can use the Pythagorean theorem to determine if the triangle is a right triangle

a^2 + b^2 = c^2

12^2 + 15^2 = 18^2

If this is true, then the triangle is a right triangle
