an equilateral triangle is inscribed in a circle of radius 2 cm if P lies inside the triangle then the minimum sum of distances of P from the sides of the triangle is _______

see for the sum of distances to be minimum i think the distance to each side should be minimum...
Which means the point p should be the intersection point of the three altitudes..
as it is given an equilateral triangle so the point p will be the centre. . .
If you take a small triangle with two sides as the radius and the distance from the side..then u get a relation
2 * sin 30 = Distance req
so d=1
so now the minimum sum = 1+1+1 =3
i hope its  correct
