Introduction

In geometry, a right triangle is a triangle in which one of the angles is a right angle, i.e., 90 degrees. To determine if a triangle is a right triangle, we can use the Pythagorean theorem, which states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

The Pythagorean Theorem

The Pythagorean theorem is a fundamental concept in geometry and trigonometry. It is named after the ancient Greek philosopher and mathematician Pythagoras, who is credited with its discovery. The theorem is stated as follows:

a^2 + b^2 = c^2

where a and b are the lengths of the two sides that form the right angle, and c is the length of the hypotenuse.

Applying the Pythagorean Theorem to the Given Triangle

In this problem, we are given a triangle with sides of lengths 32, 60, and 68. To determine if this triangle is a right triangle, we can use the Pythagorean theorem. We will assume that the side of length 68 is the hypotenuse, since it is the longest side.

Step 1: Square the Lengths of the Two Sides

First, we need to square the lengths of the two sides that form the right angle. We have:

a^2 = 32^2 = 1024
b^2 = 60^2 = 3600

Step 2: Calculate the Square of the Hypotenuse

Next, we need to calculate the square of the hypotenuse. We have:

c^2 = 68^2 = 4624

Step 3: Check if the Pythagorean Theorem is Satisfied

Now, we need to check if the Pythagorean theorem is satisfied. We have:

a^2 + b^2 = 1024 + 3600 = 4624
c^2 = 4624

Since a^2 + b^2 = c^2, we can conclude that the Pythagorean theorem is satisfied.

Conclusion

Based on the Pythagorean theorem, we can conclude that the triangle with sides of lengths 32, 60, and 68 is a right triangle. The side of length 68 is the hypotenuse, and the sides of lengths 32 and 60 form the right angle.

Answer

The answer is: A. True
