Question:

Which of the following describes a triangle with sides of length 10 inches, 1 foot, and 2 feet?

  1. This is an acute triangle.
  2. This is a right triangle.
  3. This triangle cannot exist.
  4. This is a right triangle.
  5. More information is needed to answer this question.

Correct Answer: C

Explanation:

One foot is equal to 12 inches, so the triangle would have sides 10, 12, and 24 inches. Since

10 + 12 = 22 < 24,

the triangle violates the Triangle Inequality, which states that the sum of the lengths of the two smaller sides must exceed the length of the third. The triangle cannot exist.
