The diagram below shows a regular pentagon.
fill in the blanks in the definition and diagram labels.
write apothem, center, or side in each blank.

1. Center: it is located in the CENTER of the pentagon, therefore, your answer is center.
2. Apothem: I'm guessing this one is the one you need help on. Apothem means a line from the center of the polygon at right angles to any of the sides
3. Side: It is pointing to a SIDE of the pentagon, which is where it's perimeter will be found

hope this helps
