The Assignment

Using Turtle Graphics, draw the Union Jack, flag of the United Kingdom $($see the picture above$).$ Note that you have to actually draw it using Python turtle graphics; you can't just include an

image of the flag downloaded from the web. I chose that flag because it's interesting to draw, consisting of several simple shapes. In fact, ifyou do it right, it only really requires two

functions. But it also requires a bit of ingenuity to get it right.

You can find details about the flag design by Googling "flag of UK$,"$ but the main facts are these: The flag has a height to width ratio of $3$ to $5.$ I would suggest drawing yours at $300x500$

pixels, or larger. The details of the flag can be found on the following specification sheet.

One thing that's not completely clear from this sheet is that the diagonal axis is at an angle of $30\mathrm{.}96$ degrees from the horizontal axis. With that, you can figure out the rest of the dimensions,

assuming your trigonometry isn't too rusty. OK$,$ sorry to scare you! I don't assume you know trigonometry. So here are some lengths you might find helpful. Consider where the white and

red diagonal stripe intersects the upper left corner of the flag. The intersection with the vertical border is approximately $3\mathrm{.}5$ and with the horizontal border is approximately $5\mathrm{.}8($using the

units of the diagram above, which is $3050).$ If you know that the stripe has width $6($with components of $3$ white, $2$ red, $1$ white$),$ you should be able to figure out the rest. Ask if you have

trouble. BTW: the red diagonals aren't continuous; that is$,$ they are two separate pieces, not a complete bar.

You must do this assignment in a modular fashion. That means defining functions to build a reusable drawing toolkit. For example, you might define a function to draw a rectangle with

parameters of the coordinates of the top left corner, width, height, and color. You can decide what functions you need, but you must have some.

And if you think about it$,$ the UK flag is just a bunch of colored polygons $($rectangles$,$ triangles, and other odd shapes$).$ I did my drawing by defining basically two functions $($in addition to

main$)$:

The first draws a closed polygon where the vertices are given as a list of pairs. Remember to return to the first pair on the list. The second function just calls the first, filling the polygon with

the color provided.
