Study Notes
- Congruence means having the same shape and size, denoted by the symbol for congruency which includes the equal sign.
- Congruence is used in mass production for various products like paper bills, coins, keys, silverware, and pony/forknighten.
- The idea of congruence helps recognize congruent figures in the same orientation, allowing for sliding, flipping, or rotating until they overlap exactly.
- Properties of triangle congruence include reflexive, symmetric, and transitive properties.
- Triangle congruence is based on corresponding parts being congruent in both angles and sides.
- Triangle parts include three sides (AB, BC, AC), three angles (A, B, C), and three vertices (A, B, C).
- Correspondence in triangles is indicated by arrowheads, with corresponding angles and sides being crucial for proving congruence.
- The sum of the three interior angles in a triangle always equals 180 degrees (Triangle Sum Theorem).
- Included side and included angle of a triangle refer to the side containing two angles and the angle between two sides, respectively.
- Opposite sides and angles in a triangle are determined by their positions relative to each other.
