Congruent Shapes - Key Concepts and Examples

Definition

• Congruent Shapes: Identical in both shape and size.
  • Important to note: Congruent shapes can be reflected or rotated.
  • Reflection or rotation might make shapes appear different but does not affect congruency.

Examples of Congruent Shapes

1. Comparing Shape A with Other Shapes
   • Shape B:
     • Congruent to A.
     • Same shape, size, and orientation.
   • Shape C:
     • Not congruent.
     • Different shape altogether.
   • Shape D:
     • Not congruent.
     • Same shape but different size.
   • Shape E:
     • Congruent to A.
     • Appears different due to reflection but maintains same shape and size.
   • Shape F:
     • Congruent to A.
     • Differently oriented due to a 90-degree counterclockwise rotation but remains same shape and size.

Practice Example

• Congruent Pair Identification:
  • Shapes A and E are congruent.
  • A is a 90-degree clockwise rotation of E or vice versa.
  • Maintain same shape and size, confirming congruency.
