Through the centroid of an equilateral triangle, A line parallel to the base is drawn. On this line an arbitrary point P is taken inside the triangle. Let h denote the bot^("lar") distance of P from the base, h_1 h_2 are bot^("lar") distances from other two sides then

Answer»

`h=(h_(1)+h_(2))/(2)`
`h=SQRT(h_(1)h_(2))`
`h=(2h_(1)h_(2))/(h_(1)+h_(2))`
`h=((h+h_(2))sqrt(3))/(4)`
