This guide will help you determine if a given triangle is a right triangle. To do this, you'll represent the length of the longest side as 'c' and check if the side lengths satisfy the equation c² = a² + b². If they do, the triangle is a right triangle; if not, it is not a right triangle. Examples include side lengths such as 10, 11, 14.2 and 4, 4.3, showcasing the verification process. Practice identifying right triangles using various side lengths with your guided practice on this topic.
