What shape has a exterior angle of 45 degrees?
Any shape can have an exterior angle of 45 degrees. If you are talking about exterior angle sum, it is always 360 degrees for any polygon. If you are talking about a regular polygon (equal exterior angles), it would be 360/45=8 sides. Therefore, a regular octagon has exterior angles of 45 degrees.
If the exterior angle of a regular polygon equals 72 degrees what shape is the polygon?
Pentagon A+
If the exterior angle of a regular polygon equals 36 degrees what shape is the polygon?
It is a regular 10 sided decagon
What shape has 9 equal sides?
A regular nonagon.
What shape has 150 in each interior angle?
If the interior angle is 150° then the exterior angle measures 180 -150 = 30°. The sum of the exterior angles of a regular or convex polygon = 360° The number of sides is therefore 360/30 = 12 sides The shape is a dodecagon.
What is a regular polygon called if one exterior angle equals 40 degrees?
A nine sided shape that is called a regular nonagon.
What shape has a exterior angle of 45 degrees?
Any shape can have an exterior angle of 45 degrees. If you are talking about exterior angle sum, it is always 360 degrees for any polygon. If you are talking about a regular polygon (equal exterior angles), it would be 360/45=8 sides. Therefore, a regular octagon has exterior angles of 45 degrees.
Is nonagon regular shape?
A nine sided nonagon is only a regular shape if it has 9 equal sides
How many degree is each interior angle of a regular nonagon?
Each interior angle of a regular 9 sided shape measures 140 degrees
What is the interior of a regular nonagon?
It is a plane area in the shape of a nonagon!
Interior angle for 20 sided shape?
Exterior angle = 360/20=18 interior angle = 180 - 18 = 162 Must be regular shape
If the exterior angle of a regular polygon equals 90 degrees what shape is the polygon?
square
If the exterior angle of a regular polygon equals 72 degrees what shape is the polygon?
Pentagon A+
What is the size of each angle in a regular 25 sided shape?
Exterior angle = 14.4 degrees Interior angle = 165.6 degrees
If the exterior angle of a regular polygon equals 36 degrees what shape is the polygon?
It is a regular 10 sided decagon
One exterior angle of a regular polygon measures 30 what is the sum of the polygons exterior angle measures?
If the exterior angle is 30o then the shape has 360/30 = 12 sides. An interior angle = 180 - exterior angle = 180 - 30 = 150. Since the shape has 12 sides the interior angles sum to 150 x 12 = 1800o.
What is the exterior angle of an 20 sided shape?
If it's regular then 360/20 = 18 degrees
