**1. Find AD**
* **Proportion:** 3/AD = AD/6
* **Calculate AD:**
AD = √(3 * 6)
AD = √18
AD = 3√2
**2. Find BD**
* **Proportion:** BD/3 = 3/6
* **Calculate BD:**
BD = (3 * 3) / 6
BD = 1.5

The problem missed to define that triangle ABC is a right angled triangle.

So, this post is FATALLY INCORRECT.

Where do you find such gibberish ?

And WHY do you post gibberish to this forum ?
