A triangle has sides with lengths 7 meters, 4 meters, and 5 meters. Is it a right triangle
1 answer
Yes, it is a right triangle. This is known as a Pythagorean triple, meaning that the lengths of the sides satisfy the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides. In this case, 7^2 + 4^2 = 5^2, so the triangle is a right triangle.
