b. medians
c. lines containing the altitudes

Step-by-step explanation:

The complete question is

For a triangle, list the respective names of the points of concurrency of (a) perpendicular bisectors of the sides (b) bisectors of the angles (c) medians (d) lines containing the altitudes.

Images are attached.

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
