Which of the above shapes are regular
polygons?

@Answer 2,1,0,1

@Feedback E0.666666667,?,?,?
@Feedback 0,?,?,?

@FeedbackC 0,A regular polygon must have equal length sides
@FeedbackC 0,and corner angles.  Only the centre shape is
@FeedbackC 0,not a regular polygon.*

@Answer 1,120

@Feedback 0,?

@FeedbackC 0,The total of all angles in any hexagon is always 720░.
@FeedbackC 0,All six angles of a regular hexagon are equal, so to
@FeedbackC 0,find the angle of each, divide 720░ by 6 = #b120░#

@Answer 1,540

@Feedback 0,?

@FeedbackC 0,All 5-sided polygons (pentagons) have a total of #b540░#,
@FeedbackC 0,whether they are regular or irregular.*

@FeedbackC 0,You can calculate the total angle of any polygon
@FeedbackC 0,by plugging the number of angles (á) into this
@FeedbackC 0,formula...*
@FeedbackC 0,      (á-2) ╫ 180░
@FeedbackC 0,      (5-2) ╫ 180░
@FeedbackC 0,            3 ╫ 180░ = #b540░#
