The points D and E are taken on the sides AB and AC of ∆ABC such that AD = 1/3 AB, AE = 1/3 AC. If the length of BC is 15 cm, then the length of DE is :
-
- 10 cm
- 8 cm
- 6 cm
- 5 cm
- 10 cm
Correct Option: D
On the basis of given in question , we draw a figure triangle ABC ,
| = | = | AB | AC | 3 |
| ∴ | = | BC | 3 |
| ⇒ DE = | = 5 cm | 3 |
