Recall that ref, denotes a reflection of R about a line L

Recall that ref, denotes a reflection of R about a line L passing through the origin. Let L, and La be two lines in R passing through the origin at angles a and 8 relative to the x-axis. Identify the composition ref, o ref as either a reflection or a rotation and specify either the line of reflection (its angle relative to z-axis) or the angle of the rotation.
