## Line-Plane AngleThe angle between a line, r, and a plane, π, is the angle between r and its orthogonal projection onto π, r'. That is, the angle between a line and a plane is equal to the complementary acute angle that forms between the direction vector of the line and the normal vector of the plane. Let's name θ to the angle which line makes with plane, n=(A,B,C) the normal vector of the plane.Determine the angle between the line:
Solution:
Therefore
θ=45º Determine the angle between the line
and the plane Solution:
θ=22.91º |
