What is the supplementary angle of a 24 sided polygon?
A polygon (with more than 3 sides) can have an angle of any measure between 0 and 360 degrees. If it is a reflex angle, it cannot have a supplement. Even if a supplementary angle exists, its size is indeterminate.
What is the measure of the interior angle of a 12 sided regular polygon?
The measure of each interior angle of a dodecagon, which is a 12 sided regular polygon, is 150o. This is found in any polygon by multiplying 2 less than the number of sides by 180o and then dividing the product by the number of sides. A dodecagon interior angle is then 10 x 180o/12 = 150o.
What is a concave pentagon?
It is a five sided polygon. At least one interior angle is greater than 180 degrees. This causes some of the vertices of the pentagon to point in toward the center. An alternate definition is there exists a line that will cut the polygon in 4 or more places.
What is the sum of angle?
An acute angle is greater than 0 but less than 90 degrees A right angle is 90 degrees An obtuse angle is greater than 90 but less than 180 degrees A reflex angle is greater than 180 degrees Exterior angles of any polygon add up to 360 degrees
Which regular polygon has interior angles with measures greater than 130?
For the interior angle of a regular polygon to be greater than 130° then the exterior angle must be less than 50°. The exterior angles of a regular polygon total 360°. 360/50 = 7.2 ....this needs to be rounded up to the next whole number. Therefore a regular polygon with 8 or more sides has interior angles measuring 130° or greater.
