How many lines of symmetry does a scalene triangle have?

 0

A scalene triangle has 0 lines of symmetry because none of its sides or angles are equal. To understand this, let's break it down:

• Definition of Symmetry: A line of symmetry in a shape is an imaginary line that divides the shape into two identical halves. Each half is a mirror image of the other.
• Scalene Triangle Characteristics: In a scalene triangle, all three sides and all three angles are different. This means that there is no way to draw a line through the shape such that both halves would mirror each other perfectly.
• Why 0 Lines of Symmetry? Because a scalene triangle lacks any equal sides or angles, it cannot be divided into identical mirror images along any axis. Therefore, there are no lines of symmetry in a scalene triangle.
