Explains the terminology for angles of elevation, depression, inclination, and declination. Demonstrates how to 'translate' exercises into triangles and equations.

Explains what "tangent" is and its role in the right triangle. Slope of a line is investigated and tangent for special common angles is given. Angle of elevation and angle of depression are also covered here.

The online assessment demonstrates knowledge of advanced mathematical concepts in Algebra II. The questions test students on the application of trigonometric functions.
