Slides designed to teach finding area of a triangle using sine. A total of 3 slides with space to illustrate and write during the lesson and the file you download contains a jpeg, PDF, and power point file.
Derive the formula A = 1/2 ab sin(C) for the area of a triangle by drawing an auxiliary line from a vertex perpendicular to the opposite side.
Understand and apply the Law of Sines and the Law of Cosines to find unknown measurements in right and non-right triangles (e.g., surveying problems, resultant forces).
