Formula for Finding Angles
Before learning the formulas for finding angles, let us see the situations where we may need to use these formulas. There are different formulas for finding angles depending on the available data. Let us learn the formulas of finding angles case by case here.
To find the missing angle in a polygon, we use the sum of interior angles formula.
To find the missing angle in a right-angled triangle, we use trigonometric ratios.
To find the missing angles in a non-right-angled triangle, we use the law of sines and the law of cosines.
