Question

if a straight line falling on two straight lines make the interior angles on the same side of it where sum is 120° the two straight lines if producted intelfinetly meet on the straight which is the sum of angle is​

Answer 1

Answer:

Now in order to meet line BE and DF, we need to form a triangle 

Now if we consider line AB and CD it won't meet since

base angles sum is greater than 180...(x+y=120....given) 

So, it will intersect only on AE and CF side

Since base angles x+y=120 less than 180

The two straight lines, if produced indefinitely meet on the side on

which the sum of angles is less than or equal to 120°....
