do you know your sat polygons?<\/h2>\n

a quick little formula that will make your life a lot easier in case you come across an sat problem that asks about polygons is the following:<\/p>\n

total degree measures of a polygon: 180(n \u2013 2), where n = # of sides of the polygon<\/strong><\/p>\n

say, you have to find the total degree measure of an octagon (that\u2019s the shape of a stop sign). but no need to stop here! we can just plug in \u20188\u2019 for n and we get:<\/p>\n

180(8 \u2013 2) = 180(6) = 1080<\/p>\n

another helpful formula to know is the degree measure of any one side of a congruent polygon. a congruent polygon has equal sides, and therefore equal angles. all you have to do is to take the original formula and divide by \u2018n\u2019. this makes sense because you are taking the total degree measure and finding out the measure for any one side. so that\u2019s why we divide the total degrees by the number of sides:<\/p>\n

[180(n \u2013 2)]\/n <\/strong><\/p>\n

returning to n = 8, let\u2019s assume the octagon is congruent. what is the measure of any of its sides? <\/p>\n

180(6) = 1080\/n = 1080\/8 = 160<\/p>\n

now you\u2019ve learned two useful formulas dealing with polygons!<\/p>\n

 
\ndegree measure of sides in a congruent polygon:<\/p>\n

[(n \u2013 2)180]\/n<\/strong>
