- Vashon-Maury Island is located in the middle of southern Puget Sound, midway between Seattle and Tacoma, within the boundaries of King County. Its history parallels that of the rest of the county, but its growth and development have occurred at a much slower rate, owing in main part to its inaccessibility to the mainland.
- Quadrilateral (Wikipedia)
In geometry a quadrilateral is a four-sided polygon, having four edges (sides) and four corners (vertices). The word is derived from the Latin words quadri, a variant of four, and latus, meaning “side”. It is also called a tetragon, derived from greek “tetra” meaning “four” and “gon” meaning “corner” or “angle”, in analogy to other polygons (e.g. pentagon). Since “gon” means “angle”, it is analogously called a quadrangle, or 4-angle. A quadrilateral with vertices A, B, C and D is sometimes denoted as ABCD.
