finish geo chpt 11.5 hw - p. 533 #1 - 17
NOTES (Jules - this is for you):
Area of Equilateral Triangle = (s^2)/4 x sqrt 3 (look in the book)
Area of Regular Polygon (any, including triangle) = (1/2)ap
a = apothem (segment that goes from the center of the polygon to the midpoint of a side - perpendicular bisector)
p = perimeter
r = radius (segment that goes from the center of the polygon to a vertex angle of the polygon - bisects the angle)
KNOW YOUR 30-60-90 and 45-45-90 triangles!!
