There are four categories of oblique triangles that can be solved and whose names express what is known about the side lengths and angle measurements.
An SAA triangle is one where the length of one side is known together with the measures of an adjacent angle and an opposite angle.
An SSA triangle is one where the measure of an angle is known together with the lengths of an adjacent side and an opposite side.
An SAS triangle is one where the lengths of two sides are known together with the measure of the included angle
And finally an SSS triangle is one where the lengths of all three sides are known.
