Precalculus: Relatives of the Sine Law

Objectives

• Students will make conjectures about the types of triangles for which certain variations of the Law of Sines are true.
• Students will verify conjectures using algebraic and trigonometric methods.

Vocabulary

• Law of Sines
• Law of Cosines

About the Lesson

This lesson involves investigating several variations of the Law of Sines.
As a result, students will:

• Make conjectures about the type of triangles for which variations of the Law of Sines are true.
• Verify conjectures using algebra, the Law of Sines, the Law of Cosines, and other trigonometric identities.
