Question

Construct a line segments AB of length7.5 cm From this line segments,cut off a line segments AC of length 3.2 cm measure the measure the Length of the remaining line segments CB

Answer 1

Answer:

Step1 Draw a line l.Mark a point A on it.

Step2 Since length of AB is 7.8cm, we measure 7.8cm using ruler and compass.

Step3Now keeping compass opened the same length.We keep pointed end at point A, and draw an arc on line l.So the required line segment is

AB

ˉ

=7.8cm

Step4Now, we need to cut of AC of length 4.7cm.We measure 4.7cm using ruler and compass.

Step5Now keeping compass opened the same length.We keep pointed end at point A, and draw an arc on line l.

Result:The required line segment

AC

ˉ

=4.7cm
