Question

Kasey has three pieces of wood that measure 9 inches, 12 inches, and 21 inches. Can she make a right triangle

with the three pieces of wood (without cutting or overlapping)?

Answer 1

The answer would be (no)

Answer 2

Answer: No

Explanation:

Add 2 sides together. If the sum of greater than the length of the 3rd side for all 3 options it can form a right triangle if it doesn’t than it can’t:

9 + 12 = 21 which is not greater than the 3rd side length of 21 so this cannot form a right triangle.
