Konstruksjonsknapper

Du kommer til å konstruere selv med hjelp av et sett med knapper. Her er en enkel oversikt over hva hver knapp gjør.

	Flytt et punkt ved å klikke og dra.		Add a point, by moving to the position you want and clicking (or by pressing, dragging then releasing)
	Konstruer en linje gjennom to punkter ved først å klikke også dra også klikke igjen.		Use the compass to draw a circle by clicking first where the centre is, then where the circumference is and last where you want this circle positioned.
	Construct a parallel to a line by first selecting that line and then dragging to a point.		Construct a perpendicular to a line by first selecting that line and then dragging to a point.
	Construct a circle by choosing the centre and a point on the circumference.		Construct the midpoint between two given points.
	Bisect the angle between two lines.		Construct a line at a fixed angle to a given line.
	Construct a conic from 5 given points, which you specify by clicking in turn in the task window.		Measure the angle between two given lines.
	Undo your last step - and the step before that, and so on...		Gi et hint
