Angles Formed by a Transversal with Two Parallel Lines | Infinity Learn

## TL;DR

This video explains the different types of angles formed by a transversal with two parallel lines and their relationships.

## Key Insights

• 🫥 Parallel lines intersected by a transversal form four pairs of corresponding angles.
• 🧘 Corresponding angles are always equal, regardless of the position of the transversal.
• 🧘 Alternate interior angles are equal and alternate in position.
• 🟰 Consecutive interior angles are equal and are next to each other.
• 🟰 Vertically opposite angles are always equal.

## Transcript

Consider line 'p' and line 'q' which are on a plane. The lines are also parallel to each other, which would mean that they do not intersect or ever meet. And this is transversal 'R' , which cuts the lines 'p' and 'q' at two distinct points. In this video we will try to understand the different types of angles formed by the transversal with two para...

### Q: What are corresponding angles?

Corresponding angles are formed when a transversal intersects parallel lines, with each pair of angles being in the same position relative to the transversal and the parallel lines. These angles are always equal.

### Q: How are alternate interior angles defined?

Alternate interior angles are angles that are on opposite sides of the transversal and between the two parallel lines. They are equal and alternate in position.

### Q: Can you explain consecutive interior angles?

Consecutive interior angles are angles that are on the same side of the transversal and between the two parallel lines. They are next to each other and are equal.

### Q: What are vertically opposite angles?

Vertically opposite angles are formed when two lines intersect. They are located opposite each other and are always equal.

## Summary & Key Takeaways

• The transversal cuts two parallel lines, forming four pairs of corresponding angles, which are always equal.

• There are two types of interior angles: alternate interior angles and consecutive interior angles.

• Vertically opposite angles, formed by the intersection of two lines, are always equal.
