You're right on both counts!
That exterior angle is 90°.
And your area formula is correct.
Hello everyone, I do not know if I am solving this problem well,
perhaps not so simple as I see it:
Two octagons equal have a common side. Find the angle between the sides of both polygons consecutive common.Find the area of the figure if the side is 2m.
I draw on the figure I made:
And according to the following theory:
In a regular octagon, with sides and angles that are equal, the sides are joined at an angle of 135 degrees or . Each outer corner of the regular octagon is 45 º or
And so I think then that the sum 45 + 45 = 90 degrees to the exterior angle formed by the two side keys names to common.
Furthermore, the area of an octagon side is:
I am well on these considerations?
A greeting and thank you very much
