<p>Can someone explain to me how to find an apothem? It’s always been one of those things that have elluded me, and I’m pretty positive I will see it on the test.</p>
<p>if you know the radius, then you can use the pythagorasy theorem. so like (1/2side) squared + r squared = apothem so YAY!@!</p>
<p>What is an apothem?</p>
<p>EDIT: Nevermind. I remember it now.</p>
<p>in a big fat regular polygon, its like the segment that is the perpendicular bisector of a side and goes to the center. so like if you had a square s=5, the apothem length would be 1.</p>
<p>Grazi. I think I’m starting to piece it together now… :-)</p>
