In the subjects of geometry and trigonometry, a linear pair of angles is any two adjacent angles formed together to add up to 180°, or Ï€ (pi) radians. This rule is also known as the linear pair ...
The sum of the angles inside any polygon can be found by spitting the polygon into triangles. Sum of interior angles = 180(n – 2) where n is the number of sides In a regular polygon all the angles are ...
