About This MicroSim

This interactive diagram shows the defining characteristics of a linear pair - adjacent angles whose non-common sides form a straight line.

Key Properties

Property Description
Adjacent Share vertex and side
Straight line Non-common sides are opposite rays
Supplementary Always sum to 180°

How to Use

  • Hover over each part to see its description
  • Notice the angle measurements: 110° + 70° = 180°
  • See why linear pairs are always supplementary

Linear Pair Postulate

If two angles form a linear pair, then they are supplementary.

\[m\angle 1 + m\angle 2 = 180°\]

Learning Objectives

  • Recognize linear pairs
  • Apply the linear pair postulate
  • Calculate unknown angles in linear pairs

Bloom's Taxonomy Level
