In the provided image, angles are labeled 1 through 6, positioned at the origin with the angles formed between intersecting lines.

A linear pair consists of two adjacent angles whose non-common sides form a straight line, meaning they sum to 180 degrees.

Identifying Linear Pairs:

• Angles 2 and 3: These angles are adjacent and their sides combine to form a straight line. Hence, they form a linear pair.
• Angles 4 and 5: These angles are adjacent and also combine to form a straight line, so they form another linear pair.

Summary:

• Linear Pairs:
  • Angles 2 and 3
  • Angles 4 and 5
