Question

If a triangle has side measuring 60 in., 75 in., and 45in. in length, is it a right triangle?

Hint: Use the converse of the Pythagorean Theorem to check

answers:

No, because 9,225 does not equal to 2,025

yes, because 3,600 equals 3,600

no, because 5,625 does not equal to 3,600

yes, because 5,625 equals 5,625

To determine whether the triangle with sides measuring 60 in., 75 in., and 45 in. is a right triangle, we can use the converse of the Pythagorean Theorem. According to this theorem, if the square of the length of the longest side of a triangle equals the sum of the squares of the other two sides, then the triangle is a right triangle.

1. Identify the lengths of the sides:
- Side a = 45 in.
- Side b = 60 in.
- Side c = 75 in. (the longest side)

2. Calculate the squares of the side lengths:
- \( a^2 = 45^2 = 2025 \)
- \( b^2 = 60^2 = 3600 \)
- \( c^2 = 75^2 = 5625 \)

3. Check the Pythagorean condition:
- We need to check if \( c^2 = a^2 + b^2 \):
- \( 5625 = 2025 + 3600 \)
- \( 5625 = 5625\)

Since \( 5625 \) does equal \( 5625 \), this means that the triangle **is a right triangle**.

So the correct answer is:
**yes, because 5,625 equals 5,625**.
