Trigonometric Ratios

What leg is considered the hypotenuse?

• any side

• the side opposite the smallest angle

• the side opposite the right angle

• the side opposite the shortest leg

Answer explanation

The hypotenuse, which is the side directly across from the right angle, is always c.

La hipotenusa, que es el lado directamente opuesto al ángulo recto, es siempre c.
