Question

Polygon with three interior angles whose sum 180 degrees

Answer 1

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!

Answer 2

Answer:

60

Step-by-step explanation:

I'm assuming you want to know the angle measures. Just divide 180 by 3 and you get 60.
