Tennis is played between two or four athletes on a court 23.77m long x 8.23m wide for singles or 10.97m wide for doubles, with a net stretched across the middle. Play begins with one player serving the ball from the right-hand side behind his/her baseline diagonally across the net into the opposite service court.
The eight taekwondo events at the Olympic Games – four weight categories for men, four for women – are played as a single elimination tournament. The winners of each contest qualifies for the next round, with the two finalists going head to head in the gold medal contest. All competitors who lost to one of the finalists enter the ‘repechage’, which eventually determines the winners of the bronze medals.
Table tennis is played on a rectangular table that is 2.74m long, 1.53m wide and 0.76m high. A net 15.25cm high is stretched across the middle of the table and a white line divides the table in two lengthwise. Players use their racquets to hit the ball back and forth across the table.
Shooting events are distinguished by the type of firearm or airgun, the type of target, whether moving or stationary, and the distance of the shooter from the target. A score from one to 10 is awarded for each shot, depending on its accuracy. In the final events, partial points can be awarded for shots that are close to the target.
