Answer 1

Answer:

GiveN:

∆ABC is a right angled triangle, right angled at C.

D is the midpoint of base BC.

To Prove:

AB² = 4AD² - 3AC²

Step-wise-Step Explanation:

Refer to the attachment for the diagram with basic information and labellings.

Using Pythagoras theoram in ∆ACD:

⇒ AC² + DC² = AD²

⇒ AC² + (BC/2)² = AD²

⇒ AC² + BC² / 4 = AD²

Multiplying 4 with the above equation,

⇒ 4AC² + BC² = 4AD² ...............(1)

Now using Pythagoras theoram in ∆ACB:

⇒ AC² + BC² = AB² ..........(2)

Subtracting eq. (2) from eq. (1),

⇒ 4AC² + BC² - AC² - BC² = 4AD² - AB²

⇒ 3AC² = 4AD² - AB²

This can be written as:

⇒ AB² = 4AD² - 3AC²

And this is what we had to prove!!
