Polygon with three interior angles whose sum 180 degrees
mojhsa [17]

Answer:

Triangle

Step-by-step explanation:

A triangle has three vertexes, and therefore three interior angles. Those angles also sum to 180 degrees because of the formula (n-2)*180, where n is the number of sides that a polygon has. Plugging in 3, you get  1\cdot 180, or just 180 degrees. Hope this helps!
