<p>I noticed on the collegeboard online practice questions you needed to know that the sum of interior angles on a hexagon is 540. Would they give you that?</p>
<p>No they don’t give you that. Look at the formulas you get on the normal Math SAT. Its exactly the same as that if I’m not wrong.</p>
<p>By the way if you are wondering, the formula for sum of interior angles of a polygon is:
180(n-2) where n is the number of sides. Thus, since a hexagon has 6 sides, n would be 6 and n-2 would be 4 and thus, the sum of the interior angles should be 180x4=720 not 540… </p>
<p>540 would be the sum of interior angles for a pentagon.</p>
<p>Good catch, because I had actually mean to say pentagon :)</p>
<p>Yeah, it’s for a pentagon. The ‘formula’ is very easy to remember because you can draw n-2 non-overlapping triangles in an n-gon.</p>
