Divider is a drafting instrument used to divide lines and transfer measurements. A divider has two needle-pointed legs, joined at the top. An adjusting screw changes the distance between the points. A proportional divider helps reduce and enlarge drawings. Its legs are pointed on both ends and crossed. The user adjusts it so that the distance between points on one end is a certain fraction of the distance between points on the opposite end. The user can then pivot the legs to change either distance. When the legs pivot, the other distance also changes, with the fractional relationship between the distances remaining the same. Dividers are a type of caliper (see Caliper ).
