Polygon Pictures
In mathematics we use different formulas to find certain measurements. In polygons, we can find the sum of the interior angles by using the formula 180(n-2).
We can then again use the formula to find one interior angle measure by finding the total angle measure first. Then divide by the total number of sides.
YOUR ASSIGNMENT:
TOTAL POINTS: 100
Example:
6 sided figure - Hexagon: Giant's Causeway in Ireland
SUM:
180(n-2)
180(6-2)
180(4) = 720*
ONE INTERIOR ANGLE:
720/6 = 120*
