[edit] Summary
Diagram describing a proof of the Pythagorean theorem; drawn with w:MetaPost and converted to w:SVG. See also Image:Pythagoras6.png for another diagram representing the same proof, with more details.
The MetaPost code is:
beginfig(1)
pair A,B,C,H,a,b,c;
C=(0,0); B=(18cm,0); A=(0cm,10cm);
marksize=0.9cm;
labeloffset := 12pt;
defaultscale:= 35pt/fontsize defaultfont;
H - C = whatever * (B-A) rotated 90;
H = whatever [B,A];
draw A--B--C--cycle withpen pencircle scaled 2bp;
draw C--H;
label.ulft("A", A);
label.lrt("B", B);
label.llft("C", C);
label.top("H", H);
labeloffset := 8pt;
label.bot("a",1/2[B,C]);
label.lft("b",1/2[A,C]);
label.urt("c",1/2[A,B]);
labeloffset := 9pt;
label.rt("h",1/2[C,H]);
draw ((1,0)--(1,1)--(0,1))
zscaled (marksize*unitvector((1,0)));
draw ((-1,0)--(-1,1)--(0,1))
zscaled (marksize*unitvector(H)) shifted H;
endfig;
end
The SVG file was created by running the following command on the input above:
mptopdf triangle.mp
and using the MetaPost to SVG Converter, which basically does the following:
pstoedit -page 1 -dt -psarg "-r9600x9600" -f sk foo-1.pdf foo-1.sk
skconvert foo-1.sk foo-1.svg
