In the following right triangle PQR,
Note: The adjacent and the opposite sides depend on the angle θ. For complementary angle of θ , the labels of the 2 sides are reversed.
Identify the hypotenuse, adjacent side and opposite side in the following triangle:
a) for angle x
b) for angle y
a) For angle x: AB is the hypotenuse, AC
is the adjacent side , and BC is the opposite side.
b) For angle y: AB is the hypotenuse, BC is the adjacent side , and AC is the opposite side.

Using the Sine Formula (the SOH formula)
The first part of this video will explain the difference between the hypotenuse, adjacent and opposite sides of a right triangle. Then it shows how to use the sine formula (the SOH formula)
