Question

Find altitude of a equilateral triangle whose sides are each 12 cm?

Answer 1

Altitude=(a√3)/2

where a is side of the triangle

=>(12√3)/2

=>6√3cm

Answer 2

Answer:

Let ABC be the equilateral triangle with AD as an altitude from A meeting BC at D.

Then, D will be the midpoint of BC. Applying Pythagoras theorem in right-angled triangle ABD, we get:

Hence, the height of the given triangle is 6√3 .
