- Brightwater Center (wta.gov)
The Brightwater Treatment Plant, which treats waste and storm waters for King County, opened in 2011. To ensure that the treatment plant would be an asset to its host community, the campus was designed to include an Environmental Education and Community Center and a 70-acre public open space with walking trails and natural wetland habitat. The Brightwater Center’s three miles of trails yield a fascinating, family-friendly hiking experience through wetlands and woodlands that serve as a protected enclave for native wildlife and plant species.
- Square (Wikipedia)
In Euclidean geometry, a square is a regular quadrilateral, which means that it has four equal sides and four equal angles (90-degree angles, π/2 radian angles, or right angles). It can also be defined as a rectangle with two equal-length adjacent sides. It is the only regular polygon whose internal angle, central angle, and external angle are all equal (90°), and whose diagonals are all equal in length. A square with vertices ABCD would be denoted ◻ ABCD.
