How to extract rows from a parent matrix based on column values from a second matrix (child)?

I have 2 matrices: Parent matrix (19564 X 5) and a child matrix (3913 X 3) (sub-matrix of parent). The 3 cols in child matrix and 1st 3 cols in parent matrix are x,y and z - coordinates.
Parent= [x,y,z,A,B]
Child= [x,y,z]
I need to extract 4th and 5th column (A and B) from parent matrix corresponding to x,y,z coordinates in child matrix.
I tried using _ ismember_ function in MATLAB, but it performs a col-wise search and I don't get the desired output.
As output, I need a 3913 X 5 matrix whose 1st 3 cols are exactly same as the child matrix and then 2 additional cols (A and B) from parent matrix.
