Scalene → It is derived from the Greek word "skalenos" (σκαληνός), meaning uneven or unequal. The term refers to a triangle with sides of different lengths, emphasizing the lack of equality among its sides.

Memory Tip

Think of a triangle with 'unequal' sides — that's what 'scalene' means, coming from the Greek word for uneven.
