Construct of length 8.3 cm. From this cut off of length 5.6 cm. Measure the length of .

Steps: 1. Draw a line l and mark a point A on it. 2. Using compass and ruler, set the opening of the compass to 8.3 cm. With A as centre, draw an arc cutting line l at point B. Thus AB = 8.3 cm. 3. Now set the opening of the compass to 5.6 cm. With A as centre, draw another arc cutting AB at point C. Thus AC = 5.6 cm. 4. Measure BC using a ruler. BC = AB AC = 8.3 cm 5.6 cm = 2.7 cm. Hence, the length of = 2.7 cm.

Steps:

Draw a line l and mark a point A on it.
Using compass and ruler, set the opening of the compass to 8.3 cm. With A as centre, draw an arc cutting line l at point B. Thus AB = 8.3 cm.
Now set the opening of the compass to 5.6 cm. With A as centre, draw another arc cutting AB at point C. Thus AC = 5.6 cm.
Measure BC using a ruler.

Construct AB of length 8.3 cm. Practical Geometry (Constructions), ML Aggarwal Understanding Mathematics Solutions ICSE Class 6.

BC = AB − AC = 8.3 cm − 5.6 cm = 2.7 cm.

Hence, the length of $\overline{BC}$ = 2.7 cm.
