A triangle is a three-sided polygon. There will be three internal angles formed, the sum of which will always equal 180°. When any two angles are known the third can be found by subtracting the addition of the two known angles from 180. In electronics angles are usually based on those around a right-angle triangle. However, complex AC phasors can result in compound angles. These can be made more understandable by adding additional lines to the diagram, thereby breaking the drawing into two or more right angle triangles. The addition of the internal angles for any one of these smaller areas will still = 180°. It is normal practice to use a triangle where the sides represent voltage or current amplitude and the angular relationship between the sides to indicate relative phase angles.
