Question

each interior angle of a polygon is 180 how many sides does it have
​

Answer 1

Step-by-step explanation:

The General Rule

Shape Sides Sum of Interior Angles

Triangle 3 180°

Quadrilateral 4 360°

Pentagon 5 540°

Hexagon 6 720°

Answer 2

your answer is

triangle

(n-2) * 180/n = 60

(n-2) * 180 = 60n

180n - 360 = 60n

180n - 60n = 360

120n = 360

n = 360/120

n = 3 sides

therefore, your answer is triangle
