Trigonometric ratios are used to find the unknown side or angle of a right-angled triangle. There are three different trigonometric ratios, \(\sin(\theta), \cos(\theta)\), and \(\tan (\theta)\). Each ...

The area of each square is 1 cm 2. There are 12 squares contained in this rectangle. The area of the rectangle is 12 cm 2. The area of a rectangle can also be calculated using the following formula.

However, an understanding of trigonometry can also be extended to non-right angle triangles to find unknown sides or angles. The Sine and Cosine rules can be applied to find any unknown side or angle ...

This file provides 2D Boolean set operations on polygons, where you can compute, for example, the intersection or union of the shape defined by point lists, producing a new point list. Of course, such ...
