The side opposite the right angle in a right triangle is also known as the hypotenuse. This is because the hypotenuse is the longest side in a right triangle and it is always across from the right angle. The other options, leg, base, and altitude, are incorrect because they all refer to sides that make up the right angle and are not directly opposite from it. The leg is the shorter side adjacent to the right angle, the base is the bottom side of the triangle, and the altitude is a line perpendicular to the base. Therefore, they cannot be considered as alternatives for the side opposite the right angle.
