Trigonometry Laws
Ambiguous Case
When using the law of sines to solve triangles, under
special conditions there exists an ambiguous case where two separate
triangles can be constructed (i.e., there are two different possible
solutions to the triangle).Source:
wikipedia.
The
law of sines states that for an arbitrary
triangle with sides a, b, and c
and angles opposite those sides A, B
and C:.....it can be proven by dividing the
triangle into two right ones and using the above
definition of sine. The law of sines is useful for
computing the lengths of the unknown sides in a
triangle if two angles and one side are known. This
is a common situation occurring in
triangulation, a technique to determine
unknown distances by measuring two angles and an
accessible enclosed distance.

Law
of Cosines
In
spherical trigonometry, the law of cosines (also called the
cosine rule for sides is a theorem relating the sides and angles of
spherical triangles, analogous to the ordinary
law of cosines from plane
trigonometry. Source:
Wikipedia
Law
of Tangents In
trigonometry, the law of tangents[
is a statement about the relationship
between the lengths of the three sides of a
triangle and the tangents of the angles.

Right Triangle
A right triangle is composed of a right angle,
the angle at C, and two
acute angles, which are angles less than
a right angle. Source:
