Question

the points P, Q, R, s are collinear if points S, T, A, B are collinear, then the points P, Q, R, S, T, A, B are all collinear explain your answer with the help of the diagram ​​

Answer 1

The two points P,Q,R,S are collinear.If points S,T,A,B are collinear,then will the points P,Q,R,S,T,A,B always be

PQRS is co-linear

STAB is co-linear

only one point is common

Hence it is not necessary that  PQRSTAB will be colinear

P     Q    R    S

                    T

                    A

                    B

Above in the Picture PQRS is colinear , STAB is Colinear

but PQRSTAB is not colinear

P  Q  R   S  T  A  B - Here PQRS , STAB & PQRSTAB all are colinear
