What are angles called that are formed between two parallel lines cut by a transversal?

Angles that are formed between two parallel lines cut by a transversal are referred to as interior angles. This terminology is important because it helps to categorize the angles based on their positions relative to the parallel lines and the transversal.

When a transversal intersects two parallel lines, it creates several pairs of angles, including the interior and exterior angles. Interior angles are located between the two parallel lines, while exterior angles are positioned outside the lines. Understanding the relationships between these angles is crucial in geometry, as it helps in recognizing properties such as alternate interior angles being equal and corresponding angles being equal as well.

In this context, naming the angles correctly is key to solving various geometry problems that involve parallel lines and transversals, and recognizing that interior angles specifically refer to those between the two parallel lines is essential to answering related questions correctly.
