Lesson: Applications on Sine and Cosine Laws Mathematics

Students will be able to

• draw a diagram to represent a real-world problem and establish whether it can be solved by using the law of sines, the law of cosines, or a combination of both,
• solve real-world problems using the law of sines, the law of cosines, or a combination of both, including finding unknown lengths and angle measures,
• solve problems described using directions (north, east, south, and west) and problems given in a wider geometric context (including problems involving circles); this also includes finding areas of triangles or parallelograms.
