How many equal sides does an equilateral triangle have?

  1. 2

  2. 3

  3. 4

  4. 5

The correct answer is: 3

An equilateral triangle is defined by having all three sides of equal length. This equality in side length is a fundamental property of equilateral triangles, which also ensures that all three interior angles are equal, each measuring 60 degrees. The uniformity of the sides is what distinguishes this type of triangle from others, such as isosceles or scalene triangles, which do not have all sides equal.
