The sum of the interior angles of a polygon with n sides is (n-2)*180 degrees.
So n = 3 gives (3-1)*180 = 180 degrees.
Incidentally, a polygon with three sides (a triangle) must be convex.
A convex polygon.
180x(N-2)(interior angle) All polygon of the sums of exterior angles is 360. (if convex)
The angles between adjacent sides of a polygon that are interior to the polygon. If the polygon is convex, the interior angles are always less than 180 degrees. If it is concave, at least one interior angle will be greater than 180 degrees.
900 degrees
A non-convex polygon is any polygon with at least one interior angle measuring at least 180 degrees. . A polygon is defined as an area enclosed by 3 or more line segments connected at their endpoints. Basically, the figure needs to be completely closed in, have no extra lines or part of lines coming out of it, and no curves. For a polygon to be convex all of its interior angles need to measure less than 180 degrees. =D
a convex polygon has 6 sides . What is the sum of the measure of its interior angles?
No. In a convex polygon the sum of the interior angles is (n-2)*180 deg where n is the number of interior angles. In a non-convex polygon this is not necessarily true.
If interior measure means interior angles, their sum is 360 degrees. Also, whether the figure is convex is irrlevant.
360 degrees
icosikaipentagon or pentacosagon
Only when the polygon is a regular convex polygon. Such as an equilateral triangle, or a square, or a regular pentagon.
180
180(n - 2) where n is the number of sides.
A convex polygon.
Yes, the angle sums will be the same regardless of whether or not it is a convex polygon.
A polygon can be convex, which means Convex Polygon: A polygon that has all interior angles less than 180° Concave Polygon A polygon that has one or more interior angles greater than 180° A Complex polygon is neither convex or concave. A star polygon is an example of a complex polygon. If you look in google images, there are tons of pics of them.
