Alternate interior angles theorem with parallel lines
👉 Learn about parallel lines and a transversal theorems. Two lines are said to be parallel when they have the same slope and ...
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 ...
Polygons can be regular or irregular. If the angles are all equal and all the sides are equal length it is a regular polygon. To find the sum of interior angles in a polygon divide the polygon into ...
