Lesson: Ambiguous Case of the Law of Sines Mathematics

Students will be able to

• recognize when the use of the law of sines, to find an unknown length, can give rise to an ambiguous answer due to the possibility of two possible solutions (namely, when you are given two side lengths and a nonincluded, acute angle),
• recognize that the use of a calculator will default to the acute version of the ambiguous triangle case,
• solve an ambiguous triangle using the law of sines.
