Question

find the altitude of equilateral triangle when each of its side is 'a' cm

Answer 1

altitude -- squre root3/2 x a

Answer 2

Solution :-

We have to find the altitude of the equilateral triangle and length of each of its side is given.

Each side of the equilateral triangle = 'a' cm

Then, 

Height of an equilateral triangle = (Side*√3)/2

⇒ (a*1.732)/2

⇒ 1.732a/2

So, altitude of the given equilateral triangle is 1.732a/2
