Construct AB of length 7.8 cm. From this, cut off the AC of length 4.7 cm. Measure BC
With the help of a ruler and a compass, we can draw a line segment by following steps:
Given: Length of AB = 7.8 cm and length of AC = 4.7 cm.
Steps of construction:
Step 1: Construct a line l and mark a point A on it.
Step 2: Place zero mark of the ruler at A.
Step 3: Expand the compasses up to 7.8 cm and mark a point B at a distance of 7.8 cm from point A.
Hence, AB is the line segment of 7.8 cm
Step 4: Put the pointer of compasses at point A and mark another point C at a distance of 4.7 cm from A such that AC = 4.7 cm.
Step 5: Now, measure the length of points B and C.
We find that BC = 3.1 cm.
