Introduction
The purpose of this project is to explore different oblique triangles using the CDF software
starting with a right angled triangle. A relationship is thus obtained between angles and their
corresponding opposite sides. By the end of the project one will have learnt how the cosine and
sine law are derived and applied.
Exploring Ratios
Sine Law: The ratio between an interior angle and its opposite side is the same for all the interior
angles with their opposite sides (Thomas, 2007).
That is:
sinA sin B SinC
