Step-by-step explanation:
Constructing a line Po such that its length is twice of line segment AB.
Draw a line segment AB = 3.9 cm.
Draw a line ll .
Mark a point P on this line.
Measure 3.9 cm from compass and draw an arc on line. Mark this point as C.
From C and with same radius, draw another arc on line ll . Mark this point as o
This is the required line PQo
Verification:
P0 = QC + CP
= 3.9 + 3.9
= AB + AB
= 2AB
Therefore, PO is the line with a length twice that of AB.
