Hi Hemavathi,
Try these to draw, successively, points at the vertices of a pentagon, 
the outline of a pentagon and a filled pentagon. To rotate the pentagon, 
add the rotation in radians to the two sequences.

xpos<-cos(seq(0,2*pi,by=2*pi/5))
ypos<-sin(seq(0,2*pi,by=2*pi/5))
plot(xpos,ypos,pty="s")
lines(xpos,ypos)
polygon(xpos,ypos,col="red")
