Ice Hockey

"The blue lines divide the rink into three zones. The central zone is called the neutral zone or simply centre ice. The generic term for the outer zones is end zones, but they are more commonly referred to by terms relative to each team. The end zone in which a team is trying to score is called the attacking zone or offensive zone; the end zone in which the team's own goal net is located is called the defending zone or defensive zone.
The blue line is considered part of whichever zone the puck is in. Therefore, if the puck is in the neutral zone, the blue line is part of the neutral zone. It must completely cross the blue line to be considered in the end zone. Once the puck is in the end zone, the blue line becomes part of that end zone. The puck must now completely cross the blue line in the other direction to be considered in the neutral zone again." [Ice hockey rink. Wikipedia]

"In ice hockey, a play is offside if a player on the attacking team enters the offensive zone before the puck, unless the puck is sent or carried there by a defending player. When an offside violation occurs, a linesman will stop play. A faceoff is then held at a neutral ice spot closest to the infraction to restart play. ...
The National Hockey League (NHL) and International Ice Hockey Federation (IIHF) apply similar rules for determining offside. A player is judged to be offside if their skates completely cross the blue line dividing their offensive zone from the neutral zone before the puck completely crosses the same line. In both organizations, it is the position of a player's skates that are important. They cannot use their stick or other part of their body to remain onside. The lone caveat to this rule is that an attacking player's skates may precede the puck into the attacking zone when they are skating backwards and if they are in control of the puck."

"Markings.
Lines.
The centre line divides the ice in half crosswise. It is used to judge icing, meaning that if a team sends the puck across the centre line (red line), blue line and then across the goal line (that is to say, shoots or dumps the puck past the goal line from behind their own side of the centre line) it is said to be icing. ...
Faceoff spots and circles.
There are 9 faceoff spots on a hockey rink. Most faceoffs take place at these spots. There are two spots in each end zone, two at each end of the neutral zone, and one in the centre of the rink.
There are faceoff circles around the centre ice and end zone faceoff spots. There are hash marks painted on the ice near the end zone faceoff spots. The circles and hash marks show where players may legally position themselves during a faceoff or in game play. ...
Spot and circle dimensions.
Both the center faceoff spot and center faceoff circle are blue. The spot is a solid blue circle 12 inches (30 cm) in diameter. Within the spot is a center, a circle 30 feet (9.1 m) in diameter, painted with a blue line 2 inches (5.1 cm) in width.
All of the other faceoff spots have outlines 2 inches (5.1 cm) thick, forming a circle 2 feet (0.61 m) in diameter measured from the outsides of the outlines, and are filled in with red in all areas except for the 3 inches (7.6 cm) space from the tops and bottoms of the circles, measured from the insides of the outline. ...
Goal posts and nets.
At each end of the ice, there is a goal consisting of a metal goal frame and cloth net in which each team must place the puck to earn points. According to NHL and IIHF rules, the entire puck must cross the entire goal line in order to be counted as a goal. ...
Goal area.
The crease is a special area of the ice designed to allow the goaltender to perform without interference. In most leagues, goals are disallowed if an attacking player enters the goal crease with a stick, skate, or any body part before the puck. For the purposes of this rule, the crease extends vertically from the painted lines to the top of the goal frame. ...
Goaltender trapezoid.
During the 2004-05 American Hockey League (AHL) season, an experimental rule was implemented for the first seven weeks of the season, instituting a goaltender trap zone, more commonly called the trapezoid in reference to its shape. Under the rule, it is prohibited for the goaltender to handle the puck anywhere behind the goal line that is not within the trapezoidal area. If they do so they are assessed a minor penalty for delay of game. ...
Referee's crease.
The referee's crease is a semicircle ten feet in radius in front of the scorekeepers bench." [Ice hockey rink. Wikipedia]

"The neutral zone trap (often referred to as simply the trap) is a defensive strategy used in ice hockey to prevent an opposing team from proceeding through the neutral zone (the area between the blue lines) to force turnovers. The strategy is generally used to level the playing field for teams that are not as offensively talented as their opponents, although the trap can also be used by teams simply looking to protect a lead late in the game. The trap was innovated by the Toronto Maple Leafs in the 1920s and 1930s, and more recently in the mid to late 1990s and early 2000s by the New Jersey Devils." [Neutral zone trap. Wikipedia]

"An ice hockey rink is an ice rink that is specifically designed for ice hockey, a team sport. It is rectangular with rounded corners and surrounded by a wall approximately 1 meter (40-48 inches) high called the boards. ...
There are two standard sizes for hockey rinks: one used primarily in North America, the other used in the rest of the world.
International.
Hockey rinks in most of the world follow the International Ice Hockey Federation (IIHF) specifications, which is 61 metres (200 ft) × 30.5 metres (100 ft) with a corner radius of 8.5 metres (28 ft). The distance from the end boards to the nearest goal line is 4 metres (13 ft). The distance from each goal line to the nearest blue line is 17.3 metres (57 ft). The distance between the two blue lines is also 17.3 metres (57 ft).
North American.
Most North American rinks follow the National Hockey League (NHL) specifications of 200 feet (61 m) × 85 feet (26 m) with a corner radius of 28 feet (8.5 m). The distance from the end boards to the nearest goal line is 11 feet (3.4 m). The NHL attacking zones are expanded, with blue lines 64 feet (20 m) from the goal line and 50 feet (15 m) apart."
