Prove this mathematically....
Q. Given that : i 1 = r 2   a n d   r 1 = i 2
then prove that ABE is parallel to FCD.

Dear studentGiven that i1=r2 and r1=i2Refer the figure shown in figure,Now we can illustrate from i1=r2 that the interior angles are equal when a line BC crosses the two lines AE and FD. Hence the two lines ABE is parallel to FCD.Regards

  • 0
Alternate angles are equal so these lines are parallel
  • -1
Which two angles are equal ?
  • 0
Because alternate interior angles are equal. So it is a parallel
