Which technique involves redirecting an incoming blow by striking it at a right angle to its trajectory?

The technique that involves redirecting an incoming blow by striking it at a right angle to its trajectory is known as a parry. In this defensive maneuver, the defender uses their hand or arm to deflect the attacking limb away from its intended target. The key aspect of a parry is the use of an angular motion to effectively change the direction of the blow, allowing the defender to potentially create an opening for a counterattack or to create distance from the opponent.

In contrast, the guard technique typically refers to a position where the hands and arms are held up to protect vital areas, but it does not actively redirect an attack. The hook is a type of strike used in offensive scenarios rather than a defensive maneuver, and a block involves stopping or absorbing the impact of a blow without redirecting it. Understanding the distinct characteristics of these techniques is crucial for effective defensive strategies in martial arts or self-defense situations.
