AAS AAS Uses the measure of two angles and the length of the
non-included side to calculate the measure of the third angle
and the lengths of the other two sides.
AAS(angle,angle,side)
ASA ASA Uses the measure of two angles and the length of the
included side to calculate the measure of the third angle and
the lengths of the other two sides.
ASA(angle,side,angle)
SAS SAS Uses the length of two sides and the measure of the
included angle to calculate the length of the third side and the
measures of the other two angles.
SAS(side,angle,side)
SSA SSA Uses the lengths of two sides and the measure of a non-
included angle to calculate the length of the third side and the
measures of the other two angles.
SSA(side,side,angle)
SSS SSS Uses the lengths of the three sides of a triangle to
calculate the measures of the three angles.
SSS(side,side,side)
DoSolve Solves the current problem in the Triangle Solver app. The
Triangle Solver app must have enough data entered to
successfully solve that is, there must be at least three values
entered, one of which must be a side length.
DoSolve()
Example:
In Degree mode, SAS(2,90,2) returns {2.82… 45,45}.
In the indeterminate case AAS where two solutions may be
possible, AAS may return a list of two such lists containing
both results.
