The sides that form the right angle.

Answer explanation

The sides that form the right angle in a right triangle are called the 'legs'. These are the two sides that meet at the right angle, distinguishing them from the hypotenuse.

Describes the relationship between the lengths of the legs and the hypotenuse for any right triangle
