Placing a question mark at the end of a phrase does not make it a sensible question. Try to use a whole sentence to describe what it is that you want answered.
diagonal
A line segment connecting two vertices of a polygon is called an edge if the vertices are adjacent to one another. Otherwise it is called a diagonal.
A line segment in a polygon connecting any two nonconsecutive vertices is called a diagonal.
A convex polygon.
………………………… is a line segment that joins two vertexof a polygon but is not a side of the polygon.
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)
Unless the polygon is a triangle, it is a diagonal.
A line segment joining two adjacent vertices of a polygon is called an edge or a side. A line segment joining two non-adjacent vertices is called a diagonal.
It is a diagonal line segment
In a polygon, a line segment that connects two vertices is an edge, but only if they are adjacent. A line segment connecting two non-adjacent vertices is a diagonal.
