# Parallel lines for SQA National 5 Maths

This page covers the following topics:

1. Opposite angles with parallel lines

2. Corresponding angles

3. Alternate angles

When a line crosses over a pair of parallel lines, three different pairs of angles are created. One of these pairs of angles are called opposite angles.

When a line crosses over a pair of parallel lines, three different pairs of angles are created. One of these pairs of angles are called corresponding angles.

When a line crosses over a pair of parallel lines, three different pairs of angles are created. One of these pairs of angles are called alternate angles.
