I believe the angles to an equilateral seven-sided building would be 128.57 degrees on each of the outside corners. An octagon would be 135 degrees; a hexagon 120 degrees; so it makes sense it would fall in between. To achieve a square footage under 200 square feet, I believe each outside wall would be approximately 7 feet long, and the distance to the center from the middle of an outside wall just over 7 1/2 feet.
The sum of the exterior angles of any n-sided regular polygon, including a seven-sided polygon, is 360 degrees.
The interior angles of a 7 sided polygon add up to 900 degrees
A heptagon.
Exterior angles add up to 360 degrees and interior angles add up to 900 degrees in a 7 sided heptagon
No because its angles are not factors of 360 degrees
The sum of the exterior angles of any n-sided regular polygon, including a seven-sided polygon, is 360 degrees.
No because a 4 sided rectangle also has four right angles
A four-sided polygon with four congruent sides and four equal angles is a square
A seven sided shape (with seven angles) is called a heptagon.
The interior angles of a 7 sided polygon add up to 900 degrees
A seven sided object is called a septagon and the angles add up to 900 degres
A four-sided polygon with all sides congruent and with four right angles is a square.
rectangle, square
A square and a rectangle are 4 sided figures each having 4 interior 90 degree angles
In geometry, a heptagon is a polygon with seven sides and seven angles.
An irregular heptagon.
