Which of the following is used to set or measure angles when a protractor is not available? Correct Answer Scale of chords

The scale of chords is used to measure or set angles when there is no protractor. In this method, a line PQ is drawn and then from Q a perpendicular QR is drawn. An arc is drawn with centre Q and is made to intersect perpendicular QR. Then the arc is divided into 9 equal parts with each part denoting 10˚ from Q.
