Take a line segment cm long . From this segment cut off a segment of length cm with A as one end point. Measure the length of remaining segment.
STEP 1: Draw a line segment with length cm using ruler.
STEP 2: Take a compass, open it to length cm, using ruler.
STEP 3: Place the compass pointer at A and mark an arc on line segment AB.
STEP 4: Mark the point at which arc intersect line segment as C.
STEP 5: Now line segment is divided into two parts AC and CB.
cm
STEP 6: Measure length of using ruler by putting 0 mark of ruler at C.
STEP 7: Hence, length of remaining segment cm.
