Concept Used:
Postulate 10: If two parallel lines are cut by a transversal then the corresponding
Theorem 2-3: Vertically opposite angles are congruent.
Consider the given figure:
Now, linesand d is a transversal, so by postulate 10,
(Corresponding angles)
That is,
Similarly, linesand b is a transversal, so by postulate 10,
(Corresponding angles)
That is,
