Pairs of angles formed by two lines and a transversal that make an F pattern are called what?

• A. Supplementary Angles
• B. Vertical Angles
• C. Corresponding Angles
• D. Similar

Answer: (C)

When a transversal cuts two lines, the angles that sit in the same relative position at each intersection form a matching pair called corresponding angles. The F-shaped pattern comes from tracing the transversal and the two lines and noting those matching positions across the two intersections. These angles are congruent when the two lines are parallel, which is a key fact used to prove parallelism. Vertical angles, by contrast, are opposite angles at a single intersection, and while supplementary angles add to 180, they’re not the matching pair across two intersections. Similar describes a relationship between whole figures, not a specific angle pair. So the pair described by that F pattern is corresponding angles.
