Context: The NBA high school draftees are players who have been drafted to the National Basketball Association (NBA) straight out of high school without playing basketball at the collegiate level. The process of jumping directly from high school to the professional level is also known as going prep-to-pro. Since 2006, the practice of drafting high school players has been prohibited by the new collective bargaining agreement, which requires that players who entered the draft be 19 years of age and at least one year removed from high school. Contrary to popular belief, the player does not have to play at least a year in college basketball, as the player can choose to instead play in another professional league (like the NBA G League or especially somewhere overseas) like Brandon Jennings or Emmanuel Mudiay in Italy and China respectively, simply take the year off, such as the case with Mitchell Robinson, or even hold themselves back a year in high school before declaring for the draft, like with Satnam Singh Bhamara or Thon Maker.
 Question: does the nba draft out of high school Context: In several geometries, a triangle has three vertices and three sides, where three angles of a triangle are formed at each vertex by a pair of adjacent sides. In a Euclidean space, the sum of measures of these three angles of any triangle is invariably equal to the straight angle, also expressed as 180 °, π radians, two right angles, or a half-turn.
 Question: do all angles in a triangle add up to 180 Context: National Geographic Channel HD is available in the UK and Ireland. It launched on 22 May 2006 on Sky channel 543. The channel joined Virgin Media's cable TV line-up on 30 July 2009. On 5 August 2009, it was also made available on UPC Ireland's cable TV service. The HD version available in the UK and Ireland was not originally a simulcast of the standard definition version of the National Geographic Channel, with some of the content coming from Rush HD, however from 1 December 2010 National Geographic Channel HD became a simulcast.

Besides recreational ice skating, some of its uses include ice hockey, bandy, rink bandy, ringette, broomball, speed skating, figure skating, ice stock sport and curling as well as exhibitions, contests and ice shows. There are two types of rinks in prevalent use today: natural, where freezing occurs from cold ambient temperatures, and artificial (or mechanically frozen), where a coolant produces cold temperatures in the surface below the water, causing the water to freeze. There are also synthetic ice rinks where skating surfaces are made out of plastics.
 Question: is it cold in the ice skating rink Context: A partially ordered set is a bounded lattice if and only if every finite set of elements (including the empty set) has a join and a meet. For every element x of a poset it is trivially true (it is a vacuous truth) that ∀ a ∈ ∅ : x ≤ a (\displaystyle \forall a\in \varnothing :x\leq a) and ∀ a ∈ ∅ : a ≤ x (\displaystyle \forall a\in \varnothing :a\leq x) , and therefore every element of a poset is both an upper bound and a lower bound of the empty set. This implies that the join of an empty set is the least element ⋁ ∅ = 0 (\displaystyle \bigvee \varnothing =0) , and the meet of the empty set is the greatest element ⋀ ∅ = 1 (\displaystyle \bigwedge \varnothing =1) . This is consistent with the associativity and commutativity of meet and join: the join of a union of finite sets is equal to the join of the joins of the sets, and dually, the meet of a union of finite sets is equal to the meet of the meets of the sets, i.e., for finite subsets A and B of a poset L,
