The answer will depend on what measure you are interested in: interior or exterior angles, lengths of sides, principal diagonals, apothem, area.
Measure them with a protractor
30o
Measure the lengths of corresponding sides. Then divide the length from the altered polygon by that from the original.
-- Take the number of sides in the polygon. -- Subtract 2. -- Multiply the result by 180 degrees. -- You got it.
well to find the area of an object, you multiply the length and height. si measure each of it's sides, and multiply together. that's how you find the polygon's area.
40 sides
The exterior angles of any polygon add up to 360 degrees
Subtract the interior angle from 180
Measure them with a protractor
AnswerIt is Dodecagon.To find this, you have to first find the exterior angle of the polygon. Since the exterior angle of a polygon is always supplementary to the interior angle, you subtract the measure of the interior angle from 180. 180-150=30. Now You divide 360 by the measure of the exterior angle to get the number of sides of the polygon. 360/30=12. A 12-sided polygon is called a dodecagon
This figure is a regular 12-sided polygon. Find m<4
If its a regular polygon then 180-interior angle and divide the answer into 360 which will give the number of sides of the polygon.
30o
a 7 sided polygon is heptagon and the interior angle of it is 128.57 degrees.
Measure the lengths of corresponding sides. Then divide the length from the altered polygon by that from the original.
This figure is a regular 12-sided polygon. Find m<4
It will have 10 equal sides
