Looking at the ratios of the sides of right angle triangles, we can notice certain patterns if we measure different right angle triangles with the same angles. Very similar to how ratios exist in circles with circumference and diameter to discover Pi. We can then make trig (trigonometry) tables for all the angles and then draw the graph of sin(x) which forms the sine wave. These trig ratios help us finding missing angles or sides in triangles by using SOHCAHTOA (SOH CAH TOA). The sine function can be obtained by taking ratios of triangle sides at different angles.
