How to plot a straight line in polar coordinate system

I would like to plot a straight line in polar that is at 90 and 270 degree, and also a line at 0 degree. The line should have a length of 54.

Is the goal that the lines pass through the origin of the polar coordinate system, extending radially out to a radius of 54?

Yes, I would like to have the line pass through the origin. With a radius of 54.

Try this:

figure(1)
polar([0 90 270; 0 90 270]*pi/180, [0 0 0; 1 1 1]*54)               % Use ‘polar’

figure(2)
polarplot([0 90 270; 0 90 270]*pi/180, [0 0 0; 1 1 1]*54)           % Use ‘polarplot’

I will post the plot image if you want me to.
