You should be familiar with the circle method from previous activities. For example, turtle.circle$(20)$ draws a circle with a radius of $20.$ Recall from Activity $1\mathrm{.}1\mathrm{.}2$ that you can specify a second parameter, the extent of the circle, to draw an arc. For example, turtle.circle$(20,180)$ will draw one half of a circle with radius $20.$

Step $36$: Use this code editor to experiment with drawing arcs.

Change the radius and extent parameter values of circle.

Change the to$\_$angle in setheading.

Experiment with both positive and negative parameter values. import turtle as trtl

painter $=$ trtl$.$Turtle$()$

painter.pensize$(5)$

# draw curved arc

painter.penup$()$

painter.goto$(0,-20)$

painter.pendown$()$

painter.circle$(100,180)$

# draw segmented arc

painter.penup$()$

painter.goto$(0,20)$

painter.pendown$()$

painter.circle$(100,180,3)$

wn $=$ trtl$.$Screen$()$

wn$.$mainloop$()$ In your spider program, use the circle and setheading methods in an iteration$/$looping algorithm to draw curved legs on a bug instead of straight ones. Change the direction of the circle using a positive or negative extent value.

Use the penup and pendown methods to stop drawing after the extent of the circle is drawn. $($Otherwise you will draw the path back to the center of the spider.$)$

Opposite sides of the spider$$s body do not need to be exactly opposite to get a $$spidery$$ effect. Add a head to the spider by drawing a smaller circle close to the body of the spider and change the eye location. A possible variation of your spider image is shown; yours may look quite different
