Clearly, there is a good deal of subjectivity in distinguishing good from bad, but there. may be some basic characteristics that mark out a research paper from any other kind of. paper, and it is good research papers that we would like to encourage at the annual. conference.
The line segments forming a polygon are called its sides. It has three or more sides and three or more interior angles. The point of intersection of two consecutive sides of a polygon is called as the vertex of the polygon.
A Trapezoid is a 4-sided polygon (Quadrilateral) which has at least one pair of parallel sides. The sides of a Trapezoid that are parallel are called the bases of the trapezoid and the other two sides are called the legs or the lateral sides. The perpendicular distance from one base to the other is called the altitude of a trapezoid.
