To stop half-way we should ask the Turtle to take 180 steps instead of 360, keeping everything else the same.

We do indeed get a semi-circle!

The procedures for drawing semi-circles would derive easily from the circle procedures by just replacing the repeat count 360 with 180.

Note that input 'c' specifies the circumference of the full circle . So, the length of the semi-circle would be c/2.

Let's test these procedures to draw a bunch of semi-circles.

Do you see the 3 semi-circles that we drew one after the other?
