The line parallel to lines AD BC is at the midpoints of lines AB and DC and is called the median or. So the perimeter of a regular hexagon is six times the length of one side. The angle between the adjacent sides of a parallelogram may vary but the opposite sides need to be parallel for it to be a parallelogram.
Opposite sides are equal and parallel. See Area of a Regular Polygon For irregular polygons things are a little harder since there no general formulae. Area ½ d_1 d_2 sin x where.
The Varignon parallelogram exists even for a. The Area is the base times the height. There are two diagonals for a parallelogram intersecting each other at certain angles.
