How do I calculate the angle between two lines in three dimensions? Axis with angle magnitude (radians) I use a small, neat lisp routine that measures angles quite nicely in all versions. The angle between two planes is the angle between the normal to the two planes. z, Triple of points, P, Q, R, Learn how to find the angle between two lines using the formula we will go over in this video. Therefore the answer is correct: In the general case the angle between two vectors is the included angle: 0 <= angle <= 180. m 1 = and m 2 = . Euler angles can be defined with many different combinations (see definition of Cardan angles). The ang function determines the angle between two lines. The difference is the angle between them in radians. We can write the lines general direction by vector notation as: The dot product of this two vectors are related to the angle by the formula:       L. In order to find the angle bisector line equation we use the distance equations: Find the intersection point of two lines each of them defined by two pair of coordinates, first line by, The equations of two arbitrary lines are:    y = m, This equation can be easily solved by comparing the y values of both equations: m, We can see that the free item that is  a  in the line equation is equal to, Now that we have found all the values of m. And the same process accompanied with some basic algebra steps we get the y coordinate. y YXZ Given two lines. Learn more about angle, vectors, 3d ZYX XZY 1.
