  1. Let AX⊥ BC of an equilateral triangle ABC. Then the sum of the perpendicular distances of the sides of ∆ABC from any point inside the triangle is :
    1. Equal to BC
    2. Equal to AX
    3. Less than AX
    4. Greater than AX
Correct Option: B

On the basis of given in question , we draw a figure of an equilateral triangle ABC ,

Let O be a point inside the triangle.
OD ⊥ BC, OE ⊥ AC and OF ⊥ AB
AB = BC = CA
Area of (∆ OAB + ∆OBC + ∆OAC) = Area of ∆ABC

1
× AB × OF +
1
× BC × OD +
1
× AC × OE
222

Area of ∆ABC =
1
× BC × AX
2

⇒ OF + OD + OE = AX
