Additionally, the pros can hit thicker than most amateurs because they hit more softly than most amateurs, and thus "throw the balls in." It uses a coordinate system to represent geometric shapes and equations, allowing for the use of algebraic methods to solve geometric problems. WebIn order to solve this problem, students must use the fact that when an object bounces off of a wall, the angle of incidence equals the angle of reflection; that is, the angle at which the object hits the wall is equal to the angle at which the object ricochets from the wall. The pro either subconsciously makes any needed adjustment to aim while firing right at the contact point or else lines up on the ghost ball aim line but CONSISTENTLY eyes and gauges the contact point.
