Answer:
a line from the center of a regular polygon at right angles to any of its sides.
Step-by-step explanation:
a = apothem
R = circumradius
\pi = pi
{n} = number of sides
Answer:
It's the distance from the center to a side.
It's also this equation: [tex]a=R*cos(\frac{\pi }{n})[/tex]
a = apothem
R = circumradius
[tex]\pi[/tex] = pi
n = number of sides
