Chapter 8 Review for Test

Find the sum of the measures of the interior angles of each convex polygon. 

S = (n-2)180 --> n stands for the number of sides; S stands for sum

1.decagon   

2. 16-gon   

3. 30-gon

The measure of an interior angle of a regular polygon is given. Find the number of sides in the polygon.

If an interior angle measure is 150, the exterior angle angle is 30 degrees. 360/30 = 12; dodecagon

or 150n = (n-2)180

7. 150   

8. 160   

9. 175

Find the measure of each exterior angle for each regular polygon.

360/number of sides

4. 12-gon 

5. hexagon   

6. 20-gon
