Angle Relationships Summary

About This MicroSim

This visual summary chart displays all four angle relationships formed when a transversal crosses parallel lines. Hover over each panel to see it highlighted with detailed information about that relationship type.

The Four Relationships

Relationship Property Example
Corresponding Angles Congruent (≅) ∠1 = ∠5
Alternate Interior Angles Congruent (≅) ∠3 = ∠6
Alternate Exterior Angles Congruent (≅) ∠1 = ∠8
Same-Side Interior Angles Supplementary (+) ∠3 + ∠5 = 180°

How to Use

  1. Hover over each panel to highlight that relationship
  2. Observe the mini diagrams showing which angles form each pair
  3. Compare the properties - three are congruent, one is supplementary
  4. Note the patterns - position determines the relationship type

Key Insights

  • Three Congruent Pairs: Corresponding, Alternate Interior, and Alternate Exterior angles are all equal
  • One Supplementary Pair: Same-Side Interior angles add to 180°
  • Position Matters: The location of angles relative to the transversal and parallel lines determines their relationship

Learning Objectives

  • Recognize all four angle relationship types at a glance
  • Compare the properties of different angle pairs
  • Understand the pattern: most pairs are congruent, same-side interior is supplementary
