Which of the following is the correct order of steps to draw the regular octagon?

I.		Draw an isosceles triangle, \(OAB\) with \(\angle O=45^\circ,\angle A=\angle B=67.5^\circ. \)
		\(\angle O \) is the angle at the centre of the circle.
		\(\left(\dfrac{360^\circ}{8}=45^\circ\right)\)

II.		Draw a circle with centre \(O\) with the circumference passing through points \(A\) and \(B\) and divide the circle into \(8\) equal sectors.

III.		Connect all the intersecting points of the radii with the circumference of the circle to get a regular octagon \(ABCDEFGH.\)

IV.		Draw a straight line \(AB\) with \(1\text{ cm}\) length
