The sum of the exterior angles of any polygon is 360o. For a regular polygon, they are all the same, so 360o divided by the size of exterior angleo will give you how many sides the polygon has.
The interior and exterior angles of a polygon are supplementary and so sum to 180o.
So given the internal angle, subtract from 180o and then divide into 360o and you will have the number of sides.
- Interior angle = 144o
number of sides = 360o / 36o = 10 (a decagon).
- Interior angle = 140o
reader:
ext.a.=180-140=40
n. of s.=360/40=9
Thanks a lot!

How many sides does a polygon have with an interior angle of 10 degrees have?
A regular polygon cannot have an internal angle of 10 degrees and any irregular polygon can.A regular polygon cannot have an internal angle of 10 degrees and any irregular polygon can.A regular polygon cannot have an internal angle of 10 degrees and any irregular polygon can.A regular polygon cannot have an internal angle of 10 degrees and any irregular polygon can.
How many sides does a regular polygon have if the measure of an angle is 12?
The smallest internal angle possible for a regular polygon is 60 degrees. So either the angle is not 12 degrees or it is not an internal angle.
What would be one of the angle measurements of a regular polygon?
Each internal angle would be 180*(n-2)/n degrees where n is the number of sides in the polygon.
How do you work out the number of sides in a regular polygon that has an exterior angle?
With a regular polygon: 360/exterior angle = number of sides
How do you find the measure of one angle in a polygon?
For a regular polygon the internal angle between two sides is (180 - (360/n)) degrees where n is the number of sides. A regular polygon is one where all side lengths and angles are the same.

A regular polygon has an interior angle with a measure of 135how many side does the polygon have?
The number of sides of a regular polygon is 360 divided by the size of the exterior angle. The external angle is 180 - the internal angle. So for a regular polygon with an internal angle of 135 we get the following. 360 / (180 - 135) = 360 / 45 = 8 sides
How many sides does a regular polygon have if the measure of an angle is 12?
The smallest internal angle possible for a regular polygon is 60 degrees. So either the angle is not 12 degrees or it is not an internal angle.
Internal angle of 140 how many sides to the regular polygon?
That regular polygon would have 9 sides.
What would be one of the angle measurements of a regular polygon?
Each internal angle would be 180*(n-2)/n degrees where n is the number of sides in the polygon.

How do you find the measure of one angle in a polygon?
For a regular polygon the internal angle between two sides is (180 - (360/n)) degrees where n is the number of sides. A regular polygon is one where all side lengths and angles are the same.
What is the angle measure for a regular polygon?
The sum of the internal angles of an n-sided polygon is (n-2)*180 degrees. So, for a regular polygon, each internal angle is (n-2)*180/n degrees.
How do you find the internal angle of a regular polygon?
you add the other 3 internal angles together and take the answer away from 180 and the number that is left is your answer.
What is the measure of 1 angle assuming the polygon is regular?
The sum of the internal angles of an n-sided polygon is (n-2)*180 degrees. So, for a regular polygon, each internal angle is (n-2)*180/n degrees.
How can you tell if a polygon will tile plane?
A regular polygon will tile it if its internal angle divides 360 degrees.
Calculate the internal angle of a 20 sided regular polygon?
162 degrees
