The longest side of a right-angled triangle
Answer: The longest side of a right-angled triangle is called the hypotenuse. In a right triangle, the hypotenuse is the side opposite the right angle. It is always the side opposite the right angle and is the longest side in the triangle. The other two sides of the right-angled triangle are called the adjacent side and the opposite side with respect to an acute angle in the triangle. The relationship between the sides of a right triangle is defined by the Pythagorean theorem, which states that the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides. This fundamental principle is essential in trigonometry and geometry to solve various problems related to right-angled triangles.
