Understanding Triangle Types
Triangles are classified based on the lengths of their sides. The three main types are:
  • Isosceles Triangle: A triangle with at least two sides of equal length.
  • Equilateral Triangle: A triangle where all three sides are of equal length.
  • Scalene Triangle: A triangle with all sides of different lengths.

Why Equilateral?
The correct answer to the question is option 'B', Equilateral. Here’s why:
  • Equal Lengths: In an equilateral triangle, each side measures the same, which is the defining characteristic of this type of triangle.
  • Equal Angles: Along with equal side lengths, an equilateral triangle also has equal angles, each measuring 60 degrees.
  • Symmetry: The equilateral triangle has high symmetry, making it aesthetically pleasing and commonly used in various designs and structures.

Conclusion
Understanding the properties of triangles helps in recognizing their types. When a triangle has all three sides equal, it is classified as an equilateral triangle. This clear distinction makes it easy to identify and categorize triangles based on their side lengths.
