- Seattle Neighborhoods: Madrona — Thumbnail History (historylink.org)
Seattle’s Madrona neighborhood overlooks Lake Washington from the eastern rim of the city. Madrona’s hilly origins arise from the Vashon Glacier, which melted 40,000 years ago, leaving flood waters and ice to shape Lake Washington and other Pacific Northwest landmarks. Its first life was as a Native American hunting and fishing ground. Seattle was founded (in 1851), and from the 1880s to 1900, Madrona was overrun by loggers, stump farmers, berry pickers, and realtors. The beginning of the Madrona we know today was the introduction of the Union Trunk Line, which ran from the top of the hill at 34th Avenue and Union Street to Madrona Park and beach.
- 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.
