AD is perpendicular to the internal bisector of ∠ABC of ∆ABC. DE is drawn through D and parallel to BC to meet AC at E. If the length of AC is 12 cm, then the length of AE (in cm.) is
-
- 3
- 8
- 4
- 6
- 3
Correct Option: D
On the basis of given in question , we draw a figure triangle ABC ,
DE || BC and E is the mid-point of AC.
| ∴ AE = | AC | |
| 2 |
| AE = | × 12 = 6cm. | |
| 2 |
