Study Notes
- Congruence means having the same shape and size, denoted by the symbol ≅.
- The top part of the symbol for congruence indicates the same shape, while the bottom part indicates the same size.
- Congruence is used in mass production for objects like toys, paper bills, coins, and silverware sets.
- In triangle congruence, properties like reflexive, symmetric, and transitive properties are important.
- Corresponding parts of congruent triangles are congruent in terms of angles and sides.
- The sum of interior angles in a triangle is always 180 degrees (Triangle Sum Theorem).
- In included side and included angle of a triangle, the included side contains the endpoints of two angles, while the included angle is between two sides.
- Opposite sides and opposite angles in a triangle are defined relative to each other.
- Understanding the properties of congruent triangles involves identifying corresponding angles and sides accurately.
Explore the concept of congruence in geometry and its applications in triangle properties. Learn about the symbols used for congruence, triangle congruence properties like reflexive, symmetric, and transitive, the Triangle Sum Theorem, included side and included angle, opposite sides, and angles in triangles.
