Answer»

The altitude of an equilateral triangle ABC is EQUAL to ✓3/2 × side.

  • The altitude of any equilateral triangle can be calculated by the FORMULA which is :

Height of equilateral triangle = ✓3/2 × side

  • Now, equilateral triangle has three equal SIDES, so we can use length of any side to get the value of the height of the equilateral triangle.
  • In this case, we can multiply the length of AB or BC or CA.
  • And, obviously the altitude will be perpendicular to the base.
