case A)
we know that
If l and m are parallel lines
then
----> by corresponding angles
the expression is true
therefore
the answer part A) is True (see the attached figure)
case B)
we know that
If l and m are parallel lines
then
----> by corresponding angles
the expression is not true
therefore
the answer part B) is False (see the attached figure)
case C)
we know that
If l and m are parallel lines
then
----> by alternate interior angles
the expression is true
therefore
the answer part C) is True (see the attached figure)
case D)
we know that
If l and m are parallel lines
then
----> by alternate exterior angles
the expression is true
therefore
the answer part D) is True (see the attached figure)
The answer in the attached figure
