the sum of the interior angles of a 3 sided polygon is = 180 degrees.
the sum of the interior angles of any polygon is given by 540/n. in this case n is = 3
Three: it is an equilateral triangle.
An isosceles triangle has 3 sides 2 of which are congruent and 3 interior angles 2 of which are equal in size

The 3 interior angles of a 3 sided polygon which is a triangle add up to 180 degrees.
Three: it is an equilateral triangle.
Yes, an equilateral triangle can be a regular polygon because it has three equal sides and three equal interior angles.
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.
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.
An isosceles triangle has 3 sides 2 of which are congruent and 3 interior angles 2 of which are equal in size
A polygon is any plane figure bounded only by straight lines. A triangle is therefore a polygon with three sides and a pentagon is a polygon with five sides. A convex polygon has no interior angle greater than 180° . A re-entrant polygon has at least one interior angle greater than 180° . A regular polygon has all its sides and angles equal. The sum of the interior angles of a polygon is 2n - 4 right angles (n is the number of sides). The sum of the exterior angles of a convex polygon is 360° .
It's probably a triangle. A triangle has three sides and three angles.
