Concept Explanation
 

Construction of Line Segment

Construction of Line Segment: To construct a line segment of given length. There can be two situations

Case I : To draw a line segment of a given length.

Steps of Construction:

Step I: To draw a line segment  of any length.
Step II : Take a compass

Step III : Take a scale.

Step IV : Place the pointer edge on the 0 of the scale and the pencil edge at the requitred point.

Step V : Take any point on the line segment as X
Step VI: Place the pointer edge at point X and  mark an arc at line segment with the pencil edge intersecting the line segment at Y. XY is the reguired line segment.

Case II: To draw a line segment equal to a given line segment.

Steps of Construction: We are given a line segment PQ we have to draw a line segment XY equal to the length of PQ.

Step I: To draw a line segment  of any length.
Step II : Take a compass. Place the pointer edge of the point P of the given line segment. Open the compass and place the pencil edge at point Q of the given line segment.
Step III: Take any point on the line segment as X

Step IV: Place the pointer edge at point X and  mark an arc at line segment with the pencil edge intersecting the line segment at Y.

  XY is the reguired line segment.
