Two angles formed by intersecting lines and facing in the opposite direction are called what?

• A. Vertical Angles
• B. Transversal
• C. Complementary Angles
• D. Similar

Answer: (A)

When two lines cross, they create four angles around the intersection. The pair of angles that lie opposite each other across the crossing are called vertical angles. These opposite angles are always equal in measure, even though they sit on opposite sides of the intersection. This is why the term vertical angles is the correct description for the angles facing in opposite directions. The other terms don’t fit: a transversal is a line that cuts across two lines, complementary angles add up to 90 degrees, and similar describes a relationship between shapes, not a specific angle pairing.
