3. The sum of the measures of the exterior angle, one at each vertex, of any convex polygon is
degrees
4. To find the sum of the interior angles of a convex polygon with n sides, we used the equation
(formula)
5. To find the measure of each angle in a regular polygon, we used the equation​


Sagot :

Answer:

1. 180 degrees

2. 360 degrees

3. 360 degrees

4. S = (n - 2) x 180 degrees

5. (n - 2)180 divided by n

n = number of sides of the polygon
