Law of Tangents
is a statement about the relationship between the tangents of two angles of a triangle and the lengths of the opposing sides.
trigonometric function function of an angle expressed as a ratio of the length of the sides of right-angled triangle containing the angle.

Sine
Ratio of the length of the side opposite the given angle to the length of the hypotenuse of a right-angled triangle
Tangent
A line that touches a curve but does not intersect it Many people find it easy to remember what sides of the right triangle are equal to sine, cosine, or tangent, by memorizing the word SOH-CAH-TOA (see below under Mnemonics).
Terminal Side of an Angle
The ray where measurement of an angle stops.
Bearing
an angle, measured clockwise from the north direction. Below, the bearing of B from A is 025 degrees (note 3 figures are always given). The bearing of A from B is 205 degrees.
Area of Triangle
A Trigonometric Formula for the Area of a Triangle. The area of a triangle equals ½ the length of one side times the height drawn to that side (or an extension of that side).
