Full Answer

Any polygon has the same number of vertices as it does sides; this is a constant that never changes, no matter how many lines are introduced into a polygonal shape.

A collinear vertice refers to a set of points that lie on the same straight line.

Triangles are classified by the length of their sides and by the interior angles of the corners.

    What is the diagonal of a quadrilateral?

    A:

    A diagonal is a line between two vertices of a polygon that is also not a side of the polygon, and a quadrilateral is a four-sided polygon. Veritces are the points where sides of a polygon meet, and a polygon is an enclosed figure formed by three or more line segments. Using the diagonal formula n(n-3) / 2 where n is the number of sides, each quadrilateral has two diagonals.
