Final answer:
The triangle with side lengths of 14, 16, and 19 is a scalene triangle.
Step-by-step explanation:
The sides of a triangle with lengths 14, 16, and 19 do not form a right triangle since they do not satisfy the Pythagorean theorem. To determine the type of triangle, we can compare the lengths of the sides. In this case, the side lengths of 14, 16, and 19 do not satisfy any of the criteria for a special triangle (equilateral, isosceles, or right), so the triangle is considered a scalene triangle.
