Question

4) Side of equilateral triangle
= 6 cm, then altitude =​

Answer 1

Answer:

6×1.414= 8.484 is the altitude of triangle

Answer 2

Solⁿ :

By using Pythagoras theorem :

H² = B² + P²

P² = H² - B²

P² = (6)² - (3)² [ Altitude and median are same in equilateral triangle ]

P² = 36 - 9

P² = 27

P = √27

P = 3√3 cm

Therefore, 3√3 cm is the height of altitude.
