A quadrilateral is any four-sided polygon. For that reason, by definition the properties of quadrilaterals are valid for any four-sided polygon.

A triangle is a 3 sided polygon whose 3 interior angles add up to 180 degrees
The answer is 324 degrees. The general formula is (n-2)*180 degrees, where n=number of sides/vertices(both are same). But this is valid only for convex polygon (every internal angle is strictly less than 180 degrees & every line segment between two nonadjacent vertices of the polygon is strictly interior to the polygon except at its endpoints)
You can usually make valid transformations in one of the expressions until you get the other expression. A "valid transformation" in this context means one that doesn't change the value of the expression.

A valid conclusion is when your conclusion is written using the text you have and get it right.
