Each of the following questions contains two statements i.e., ASSERTION 
and REASON, and has following four choices. Only one of which is the 
correct answer. 
 
Q19. Q1. ASSERTION (A): Line joining the midpoints of two sides of triangle is parallel to the

REASON (R): If a line divides two sides of a triangle in the same ratio then it is 
parallel to the third side. 
 
 
A) Both assertion (A) and reason (R) are true and reason (R) is the correct 
explanation of assertion (A).
