उत्तर १
Draw an angle bisectcr PQ and RS of angles formed by the lines m and n. From centre draw a circle with radius 2 cm, whidi intersect the angle bisectors at a, b, c and d respectively.
Hence, a, b, c and d are the required four points.
उत्तर २
AB and CD are two intersecting lines at an angle of 30°. Their point of intersection is O.
Draw MON and ROS, the bisector of angles between AB and CD. On ON, locate a point P such that OP = 2 cm.
On OR locate a point Q such that OQ = 2 cm.
Since, P and Q are on the angle bisectors of angles between AB and CD, hence each of P and Q is equidistant from AB and CD.
Also, OP = 2 cm
Hence, P and Q are the required points.
