To construct the regular hexagon, the radius length ab is used to mark the vertices of the hexagon. can this method be used to make any regular inscribed polygon, such as a square?

Step-by-step explanation:

The main reason why it won't work to other regular polygons is beacuse the regular hexagon is the only polygon that its side is equal to the radius of the circumscribed circle. That's why won't work to other regular figures.

Therefore, the answer is no, it won't work to other regulat polygons such as a square.

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two
