What is the trapezoid in hockey?

In hockey, a trapezoid is a restricted area behind the goal line and in the corners of the rink where the goaltender is allowed to handle the puck. The trapezoid is used to limit the goaltender's ability to play the puck and prevent them from interfering with the game.

The trapezoid is typically in the shape of a trapezoid, with wider lines along the goal line and narrower lines along the end boards. The trapezoid is typically 18 feet wide and extends from the goal line to the end boards, with the top of the trapezoid starting at the goal line and extending to a point 28 feet out.

The trapezoid rule was first introduced in the NHL during the 2005-2006 season as part of several rule changes aimed at increasing scoring and reducing goaltender interference. The rule was implemented to prevent goaltenders from playing the puck in the corners and behind the net, which was seen as a strategy used to slow down the game and limit offensive opportunities for the opposing team.

Overall, the trapezoid in hockey serves to maintain a fair and balanced playing environment by restricting the goaltender's ability to handle the puck and allowing for more offensive opportunities for both teams.
