A three-sided polygon is a triangle. The angles in a triangle add up to 180 degrees.
The 3 interior angles of any triangle add up to 180 degrees
In Geometry that are many different types of polygons. The polygon whose angles equal up to 180 degrees is a triangle.
A regular polygon that has 180 degrees is an equilateral triangle.
If all of the interior angles of the polygon add up to 180 degrees, then the polygon is a triangle.

No. It is impossible.The definition of a regular polygon is a polygon with equal angles, and equal sides.For a polygon to be concave, it has to have at least one angle more than 180 degrees, and a a polygon cannot consistently have angles more than 180 degrees.

It is a triangle. The formula for the total of interior angles in an n-sided polygon is 180(n-2). This is 180 degrees for triangles, 360 degrees for quadrilaterals, and 540 degrees for pentagons.
The sum of the interior angles of any regular polygon of n sides is equal to 180(n - 2) degrees.
In Geometry that are many different types of polygons. The polygon whose angles equal up to 180 degrees is a triangle.
A regular polygon that has 180 degrees is an equilateral triangle.
all sides must be equal in length and each interior angle must be equal in degrees 90 or 180 or less than 90 degrees and 180 degrees
No regular polygon can have an interior angle of 180 degrees or more. No regular polygon can have an interior angle of 180 degrees or more. No regular polygon can have an interior angle of 180 degrees or more. No regular polygon can have an interior angle of 180 degrees or more.
A triangle. (3 - 2) x 180 [from the equation (n - 2) x180 over n] 1 x 180=180
