# Merging two line graphs into manipulate command

Ultimately the goal is to make a manipulate command and turn a line into a circle.

So I am supposed to take a line that is segmented into 12 equal lengths.

M = {{1, 0}, {2, 0}, {3, 0}, {4, 0}, {5, 0}, {6, 0}, {7, 0}, {8,
0}, {9, 0}, {10, 0}, {11, 0}, {12, 0}, {13, 0}};
Graphics[{Thin,
Line[M, VertexColors -> {Red, Blue, Orange, Green, Red, Blue,
Orange, Green, Red, Blue, Orange, Green}]}]


Then there is the circle

L = {{1, 0}, {Cos[Pi/6], Sin[Pi/6]}, {Cos[(2 Pi)/6],
Sin[(2 Pi)/6]}, {0, Sin[Pi/2]},  {-Cos[(2 Pi)/6],
Sin[(2 Pi)/6]}, {-Cos[Pi/6], Sin[Pi/6]},   {-1,
0} , {-Cos[Pi/6], -Sin[Pi/6]},    {-Cos[(2 Pi)/6], -Sin[(2 Pi)/
6]}, {0, -1},   {Cos[(2 Pi)/6], -Sin[(2 Pi)/6]}, {Cos[
Pi/6], -Sin[Pi/6]}, {1, 0}} ;

Graphics[{Thin,
Line[ { L   },
VertexColors -> {Yellow, Red, Blue, Orange, Green, Red, Blue,
Orange, Green, Red, Blue}]}]


Now I am trying to merge the two. I noticed whenever I start of with the line command I can't get it to work with manipulate.

Manipulate[Thin,
Line[ Plot[{{1, 0}, {2, 0}}, {x, 0, 3}], {a, 0, 2 Pi}  ]


So now I am not sure how to go about the problem since I can't even begin on it. Should I just use the equation of a line? That doesn't seem probably given the question

If you take a fraction f of a final vertex and a fraction 1-f of the corresponding initial vertex, and vary f between zero and one, you will find that a shape evolves from the initial shape to the final shape. Construct a Manipulate[] function with a slider that varies f that shows your straight line curling up into a circle.

Which makes me think that I need to have the individual vertices's in. Please help, thank you

Not so didactic, but the morphing follows the principle from your assignment: mathematica.stackexchange.com/a/31642/131. – Yves Klett Oct 20 '13 at 7:13

m = {#, 0} & /@ Range@13;
