IN: In Euclidean geometry, a parallelogram is a simple (non-self-intersecting) quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure. The congruence of opposite sides and opposite angles is a direct consequence of the Euclidean parallel postulate and neither condition can be proven without appealing to the Euclidean parallel postulate or one of its equivalent formulations.

IN: Open Water is a 2003 American survival horror thriller film. The story concerns an American couple who go scuba diving while on vacation in the Caribbean, only to find themselves stranded miles from shore in shark-infested waters when the crew of their boat accidentally leaves them behind. The film is loosely based on the true story of Tom and Eileen Lonergan, who in 1998 went out with a scuba diving group, Outer Edge Dive Company, on the Great Barrier Reef, and were accidentally left behind because the dive-boat crew failed to take an accurate headcount. The film was financed by the husband and wife team of writer/director Chris Kentis and producer Laura Lau, both avid scuba divers. It cost $120,000 to make and was bought by Lions Gate Entertainment for $2.5 million after its screening at the Sundance Film Festival. Lions Gate spent a further $8 million on distribution and marketing. The film ultimately grossed $55 million worldwide (including $30 million from the North American box office alone).

During the 2006 World Cup Qualifiers, controversy arose when the team's supporters rioted, interfering with the opponents' safe egress from the stadium, because of North Korea's failure to qualify. In 2009, the team qualified for the 2010 FIFA World Cup, the second World Cup appearance in their history.
