Wa languageWa (Va) is an Austroasiatic language spoken by the Wa people of Myanmar and China. There are three distinct varieties, sometimes considered separate languages; their names in Ethnologue are Parauk, the majority and standard form; Vo (Zhenkang Wa, 40,000 speakers) and Awa (100,000 speakers), though all may be called Wa, Awa, Va, Vo. David Bradley (1994) estimates there are total of 820,000 Wa speakers. Gerard Diffloth refers to the Wa geographic region as the "Wa corridor", which lies between the Salween and Mekong Rivers.
Wa StateWa State is an autonomous self-governing polity in Myanmar (Burma). It is de facto independent from the rest of the country and has its own political system, administrative divisions and army. However, the Wa State government recognises Myanmar's sovereignty over all of its territory, and the Burmese government does not consider Wa State's political institutions to be legitimate. The 2008 Constitution of Myanmar officially recognises the northern part of Wa State as the Wa Self-Administered Division of Shan State.
BisectionIn geometry, bisection is the division of something into two equal or congruent parts (having the same shape and size). Usually it involves a bisecting line, also called a 'bisector'. The most often considered types of bisectors are the 'segment bisector' (a line that passes through the midpoint of a given segment) and the 'angle bisector' (a line that passes through the apex of an angle, that divides it into two equal angles). In three-dimensional space, bisection is usually done by a bisecting plane, also called the 'bisector'.
CapA cap is a flat headgear, usually with a visor. Caps have crowns that fit very close to the head. They made their first appearance as early as 3200 BC. The origin of the word "cap" comes from the Old French word "chapeau" which means "head covering". Over time, the word has evolved and changed its meaning, but it still retains its association with headwear. Caps typically have a visor, or no brim at all. They are popular in casual and informal settings, and are seen in sports and fashion.
Line segmentIn geometry, a line segment is a part of a straight line that is bounded by two distinct end points, and contains every point on the line that is between its endpoints. The length of a line segment is given by the Euclidean distance between its endpoints. A closed line segment includes both endpoints, while an open line segment excludes both endpoints; a half-open line segment includes exactly one of the endpoints. In geometry, a line segment is often denoted using a line above the symbols for the two endpoints (such as ).
Angle bisector theoremIn geometry, the angle bisector theorem is concerned with the relative lengths of the two segments that a triangle's side is divided into by a line that bisects the opposite angle. It equates their relative lengths to the relative lengths of the other two sides of the triangle. Consider a triangle △ABC. Let the angle bisector of angle ∠ A intersect side at a point D between B and C.
Side capA side cap is a military cap that can be folded flat when not being worn. It is also known as a garrison cap or flight cap in the United States, wedge cap in Canada, or field service cap in the United Kingdom; or in vulgar slang as a cunt cap. In form the side cap is comparable to the glengarry, a folding version of the Scottish military bonnet. It has been associated with various military forces since the middle of the 19th century, as well as various civilian organizations.
Simson lineIn geometry, given a triangle ABC and a point P on its circumcircle, the three closest points to P on lines AB, AC, and BC are collinear. The line through these points is the Simson line of P, named for Robert Simson. The concept was first published, however, by William Wallace in 1799. The converse is also true; if the three closest points to P on three lines are collinear, and no two of the lines are parallel, then P lies on the circumcircle of the triangle formed by the three lines.
