A three-sided polygon is a triangle. The angles in a triangle add up to 180 degrees.
An obtuse angled triangle.
A triangle is a polygon that has three sides whose interior angles total 180 degrees.
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.
It's probably a triangle. A triangle has three sides and three angles.

regular means all sides AND angles are congruent. Therefore, a regular polygon with three sides is just a triangle. Since the angles add up to 180 degrees in any triangle, that means 180 divided by 3 = 60 degrees. Each is 60 degrees.
The sum of the interior angles for any polygon can be found by the formula 180 degrees multiplied by n-2, where 'n' is the number of sides of a polygon. If the polygon is a triangle, then the sum of the interior angles is 180 degrees because n is equal to three, the number of sides in a triangle.
