The plane passes through the center of gravity of the triangle ABC, B and C are on the same side of the plane, and a is on the other side of the plane, If the distances from a, B and C to the plane are a, B and C respectively, then the relationship between a, B and C is

The plane passes through the center of gravity of the triangle ABC, B and C are on the same side of the plane, and a is on the other side of the plane, If the distances from a, B and C to the plane are a, B and C respectively, then the relationship between a, B and C is

The center of gravity is the intersection of the three sides of a triangle
The ratio of the distance from the center of gravity to the vertex and the distance from the center of gravity to the midpoint of the opposite side is 2:1
According to the triangle similarity, we can get a = 2B = 2C
