How many ways can you find the sum of measures of the exterior angles of a polygon?
The sum of a regular polygons exterior angles always = 360
What is the formula to find the measurement of exterior angles of a hexagon?
For any n-sided regular polygon the exterior angles are 360/n degrees.
How do find the size of each exterior angle on a regular octagon?
The exterior angles of any polygon add up to 360. 360/8 = 45
How do you missing angles of a pentagon with only three angles listed?
to find the entire angle sum of a pentagon you would have to subtract 2 from 5, because 5 is the number of sides. You then take 3 and multiply it by 180. if it is a regular pentagon you just simply divide 540 by 5 (the number of angles) and that is the measure of each angle in the pentagon. If it isn't a regular pentagon you subtract the 3 angle measures you know from 540 and then with the remaining number you use thereoms and postulates and stuff to find the angle measures
What is the exterior angle of a regular dodecagon?
For any given polygon, the exterior angles will sum to 360 degrees. Thus, for a regular polygon, dividing by the number of exterior angles (the same as the number of sides) will produce the exterior angle. For a dodecagon (12 sides), 360/12=30 degrees. You can also find the interior angle easily because the interior and exterior angles are supplementary: 180-30=150 degrees for an interior angle.
Find the exterior of a regular pentagon?
the exterior of a regular pentagon is? the exterior of a regular pentagon is?
What are the exterior angles of a polygon equal to?
The sum of the exterior angles of a polygon for number of sides n is equal to 180 x (n - 2). For example, the sum of the exterior angles of a pentagon is equal to 180 x (5 - 2) = 540.To find a single exterior angle, divide this total by the number of sides - in this example, 540 / 5 = 108 degrees. Therefore, the exterior angle of a regular pentagon is equal to 108 degrees.Similarly, the exterior angle of a regular octagon is equal to 180 x (8 - 2) = 1080 / 8 = 135 degrees.
Find the measure of each exterior angle of a regular pentagon?
72 degrees
What can you conclude about the angles inside a regular polygon?
Theorem: The sum of the interior angles in a polygon with n sides is 180º(n - 2).In the pentagon below, we have labeled the interior angles 1, 2, 3, 4, and 5. Each of these is supplementary respectively to exterior angles 6, 7, 8, 9, and 10. Therefore we have: We know that angles 1 through 5 in a pentagon have a sum of 540º. We substitute 540º for these angles and we have:. Subtracting 540º from both sides, we can find the sum of the five exterior angles of this pentagon: .
How many ways can you find the sum of measures of the exterior angles of a polygon?
The sum of a regular polygons exterior angles always = 360
What is the formula to find the measurement of exterior angles of a hexagon?

How to find out how many sides a regular polygon has?
Divide one of its exterior angles into 360
How do you find interior angles non regular pentagon?
The sum of the interior angles of an n-gon is (n-2)*180 degrees - whether or not it is regular. If it is non regular you cannot find the individual angles without a lot more information.
How do you find the measure of each exterior angle of a regular pentagon?
It is: 360/5 = 72 degrees for each exterior angle and each interior angle will be 108 degrees
How do you find the number of sides a regular poly gon has by knowing the angles?
When a polygon is regular, each exterior angle is equal to the other exterior angles. Since the sum of all the exterior angles is 360 degrees, if you divide 360 by the measure of one exterior angle, you will get the number of sides. If you instead have the measure of an interior angle, simply calculate (180 - interior angle measure) to find the measure of the exterior angle, and use the above paragraph.
How do find the size of each exterior angle on a regular octagon?
The exterior angles of any polygon add up to 360. 360/8 = 45
