Calculate the height of an equilateral triangle each of whose sides measures 12 cm.
Open in App
Solution
We have the length of each side = 12cm Therefore the altitude bisects the side on which it stands into 2 equals each measuring 6cm Hence one half of the triangle being a right angled triangle will have the following measurements Hypotenus = side of the triangle = 12cm Base= half of the side on which the altitude stands = 6 cm Therefore as per the Pythagoras theorem
