In this lesson, students add the law of cosines to their repertoire of tools that can be used to analyze the measurements of triangles. To prove the law of cosines, students build squares on the sides of an oblique triangle and then analyze

The advantage to using the Law of Cosines over the Law of Sines in cases like this is that unlike the sine function, the cosine function distinguishes between acute and obtuse angles. The cosine of an acute is positive, whereas the cosine of an obtuse angle is negative. Since the sine of both acute and obtuse angles are positive, the sine of an angle alone is not enough to determine if the

The Law of Cosines NAME _____ The law of sines can be used to determine the measures of missing angles and sides of triangles when the measures of two angles and a side (AAS or ASA) or the measures of two sides and a non-included angle (SSA) are known. However, the law of sines cannot be used to determine the measures of missing angles and sides of triangles when the measures of two …

Using the Law of Cosines to Solve Oblique Triangles. The tool we need to solve the problem of the boat’s distance from the port is the Law of Cosines, which defines the relationship among angle measurements and side lengths in oblique triangles.

The Law of Cosines is presented as a geometric result that relates the parts of a triangle: While true, there’s a deeper principle at work. The Law of Interactions: The whole is based on the parts and the interaction between them.
