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.
