When constructing inscribed polygons, how can you be sure the figure inscribed is a regular polygon? a. check the distance between the angles with a straightedge. b. check the length of each side of the polygon with a compass. c. see if the diameter is the same as the length of the sides with a compass. d. there is no way to ensure you have constructed a regular polygon.

A. Check the distance between the angles with a straightedge ✖
B.Check the length of each side of the polygon with a compass ✔
C. See if the diameter is the same as the length of sides with a compass✖
D. There is no way to ensure you have constructed regular polygon✖

Most likely, B. Check the length of each side of the polygon with a compass, would be your answer for this question 

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's
