case A)
The statement is True
we know that
The measure of angle A is equal to the angle marked by corresponding angles
case B) ∠B and the angle marked are alternate exterior angles
The statement is False
Because, ∠B and the angle marked are corresponding angles
case C) because it is a vertical angle to the angle marked
The statement is True
we know that
------> by vertical angles
case D) ∠B and ∠C are supplementary angles
The statement is False
we know that
---> the sum is less than
case E)
The statement is True
we know that
and remember that
so
