How much does a four sided polygon equal??

How much WHAT does a foursided polygon equal?

How many degrees, like a triangle equals 180 degrees

http://www.mathsisfun.com/geometry/interioranglespolygons.html

The sum of the internal angles of any foursided polygon (which is also called a quadrilateral) is 360 degrees.

Sum of measures of interior angles of a polygon of n sides = (n  2 )*180 deg
polygon with 4 sides,
n = 4
(n  2)*180
(4  2)*180
2*180 = 360 
Thank You guys soo much :))

You're welcome.
