A line joining a vertex of a triangle to the mid point of the opposite side is called
Median
Centroid
Midpoint
None of these
If the vertices of a triangle are A(2,1) , B (2,7) and C(-4,-1). The relationship between BC and MN where M is the mid point of AB and N is the mid point of AC is.
MN = BC
MN = 2 BC
BC = 1/2 MN
BC = 2 MN
