Question

Fill in the blanks : The altitude of an equilateral triangle ABC is ______
​

Answer 1

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.
