True or False: The set pass is used when the ball is above head height. *
A. True
B. False

Answers

The answer is False

The statement is false because a set pass is a volley pass that must be delivered close to and over the net in order for the smasher to have an opportunity to strike it.

What is a volleyball pass?

The other team's attack comes to a halt when a volleyball pass is made. Passing also signifies the start of your team's volleyball attack. Volleyball players should try to make a good pass and send the ball to one of their teammates on the court after fending off an attack from the opposition.

The goal of a pass is to guide the ball toward the setter, who is the team's playmaker. The first person to touch the ball as it crosses the net is the passer. As previously indicated, a pass may also be referred to as a dig, serve, or bump.
