In geometry, a trapezoid is a quadrilateral, or a two-dimensional shape with four straight sides, such that it contains one pair of opposite parallel sides. A trapezoid has four angles, and because it is a quadrilateral, we know that these angles satisfy certain properties....
Polygons; Properties and Interior Angles:In geometry, polygons are defined as those planer figures that are enclosed by line segments, and at least three line segments are required to form a polygon. The polygons of three sides are known as the triangles while the polygons of...
