The underlying JavaScript code
var brd = JXG.JSXGraph.initBoard('jxgbox',{boundingbox:[-5,5,5,-5]});
var A = brd.create('point',[-2,-2]);
var B = brd.create('point',[2,-2]);
var pol = brd.create('regularpolygon',[A,B,5], {withLines:false});
for (var i=0;i<5;i++) {
brd.create('arc',[pol.vertices[i],pol.vertices[(i+2)%5],pol.vertices[(i+3)%5]]);
}
var C = brd.create('point',[-1,-1]);
var D = brd.create('point',[1,-1]);
var pol3 = brd.create('regularpolygon',[C,D,3], {withLines:false});
for (i=0;i<3;i++) {
brd.create('arc',[pol3.vertices[i],
pol3.vertices[(i+1)%3],
pol3.vertices[(i+2)%3]]);
}
