In a right angle, the two lines are the two sides of the angle that form a 90 degree angle with each other. These lines are perpendicular to each other, meaning they intersect at a 90 degree angle. The length of the two lines can vary depending on the specific triangle or shape in which the right angle is located. There is no specific calculation for the lengths of the lines in a right angle, as it depends on the context in which the right angle is being considered.
