"Know and directly apply relevant theorems such as the: • triangle angle sum theorem."
What you'll learn
- Find an unknown angle, an angle sum, or the number of sides of a convex polygon, regular or irregular, from the angle information given
- Calculate the interior angle sum of any convex polygon using (n-2)*180°, and each interior angle of a regular polygon using (n-2)*180°/n
- Apply the fact that the exterior angles of any convex polygon sum to 360°, and calculate each exterior angle of a regular polygon using 360°/n
