📚 Topic Summary
When a line (called a transversal) intersects two parallel lines, it creates several angles. Corresponding angles are pairs of angles that are in the same relative position at each intersection. If the two lines are parallel, then the corresponding angles are congruent (equal). Understanding this relationship is key to solving many geometry problems!
