Right Triangle Trigonometry

The HYPOTENUSE is directly across from the right angle.
The OPPOSITE side is directly across from the referenced angle.
The ADJACENT side is the last side. It is the side that touches the angle, but isn't the hypotenuse.

Sides of a Right Triangle

The referenced angle could be indicated by the Greek symbol "theta", by an arc marking it, or by a measure placed in the figure. It could also be marked with an "x" or other variable if you're expected to use trig to find its measure.
