**A geometric term, meaning same shape & size, denoted with a `≡`** When applied to **angles**, angles are congruent when they are the same. This involves [[Modular Arithmetic]]. - 10 degrees is congruent to 370 degrees, or: `10° ≡ 370°` When applied to **sides** they are only congruent if they are the same length. When applied to a **shape**, shapes are congruent if they are the same shape and size, translations and rotations are okay, though. When applied to **general speaking**, it just means "in agreement or harmony". **** # More ## Source - Google ## Related - [[Modular Arithmetic]]
