Congruence (9-5)
... An equal sign with a wave on top ( ) is used to indicate two figures, sides, or angles that are congruent. Tick marks ( | || ||| ) are usually used to indicate (show) congruent (equal) corresponding (matching) sides Angle signs ( ) are used mark congruent (equal) angles. Rule: Congruent figures ...
