The altitude of an equilateral triangle of side $a$ is —

a $\dfrac{a}{2}$
b $\dfrac{\sqrt{3}}{2}a$
c $\dfrac{\sqrt{3}}{4}a$
d $\sqrt{3}a$

ব্যাখ্যা

The altitude bisects the base, forming a right triangle with hypotenuse $a$ and half-base $\frac{a}{2}$ . The height is $\sqrt{a^2 - \left(\frac{a}{2}\right)^2} = \sqrt{\frac{3a^2}{4}} = \frac{\sqrt{3}}{2}a$ .
