How do you get the number of sides of a regular polygon with a given exterior angle?
By dividing the given exterior angle into 360 degrees tells you how many sides the polygon has.
How many sides does a regular polygon have with the angle 20 degrees?
If those are exterior angles, the exterior angles of any polygon add up to 360. That would be 18 sides.
How do you find the exterior angle of a polygon?
360/number of sides 180 times the number of sides the polygon has then minus 360. This gives the total sum of the exterior angles. Then to get the angle of one exterior angle divide it by the number of sides the polygon has.Very easy when you know the formula!
If the exterior angle of a polygon is 22.5 degrees how many sides does it have?
To determine the number of sides in a polygon, you can use the formula for finding the measure of an exterior angle: 360 degrees divided by the number of sides. In this case, if the exterior angle is 22.5 degrees, you would divide 360 by 22.5 to get 16. Therefore, the polygon has 16 sides.
What is the exterior angle of a regular polygon with 6 sides?
60
