Two points D and E are chosen on sides AB and AC of `Delta ABC` such that `AD=(1/3)AB` and `AE=(1/3)AC`. If BC is 15 cm long, find the length of DE.

For a triangle ABC ,D and E are two points on AB and AC such that AD=(1)/(4)AB,AE=(1)/(4)AC . If BC = 12 cm, then DE is

if D and E are points on the sides AB and AC of a DeltaABC . Such that AB=12 cm, AD=8 cm, AE=12 cm, AC= 18 cm. show that DE||BC.

if D and E are points on the sides AB and AC of a DeltaABC . Such that AB=12 cm, AD=8 cm, AE=12 cm, AC= 18 cm. show that DE||BC.

D and E are points on sides AB and AC respectively of Delta ABC such that ar (DBC) = ar EBC). Prove that DE |\| BC.

In the right-angled triangle ABC , /_B=90^(@) and the points D and E are on the sides AC and BC such that DE||AB . If AB=9cm , DE=3cm and AC=24cm , then find the value of AD .

In Delta ABC , point D and E are the points on sides AB and AC such that AB=5.6, AD=1.4, AC=7.2 and AE=1.8. Show that DE||BC.

In Delta ABC, D and E are points on side AB and AC respectively such that DE || BC and AD : DB = 3 , If EA = 3.3 cm , them find AC.

If D and E are points on the sides AB and AC respectively of DetlaABC such that AB=5.6 cm, AD=1.4 cm, AC=7.2 cm and AE=1.8cm . Show that DE||BC .
