Two line segments AB and CD are taken. Initially, the points A & C and B & D are coincident. The line segment CD is rotated about point D such that CD coincides with AB again, when it covers a distance of x. If the distance covered by C is y, the angle subtended by CD with respect to starting point is θ, then find the relation among x,y and θ. Assume that θ is in degrees.

1.	Two line segments AB and CD are taken. Initially, the points A & C and B & D are coincident. The line segment CD is rotated about point D such that CD coincides with AB again, when it covers a distance of x. If the distance covered by C is y, the angle subtended by CD with respect to starting point is θ, then find the relation among x,y and θ. Assume that θ is in degrees.
Answer» Two line segments AB and CD are taken. Initially, the points A & C and B & D are coincident. The line segment CD is rotated about point D such that CD coincides with AB again, when it covers a distance of $x$ . If the distance covered by C is $y$ , the angle subtended by CD with respect to starting point is $θ$ , then find the relation among $x$ , $y$ and $θ$ . Assume that $θ$ is in degrees.
