In an equilateral triangle ABC,AD is perpendicular to BC and AD²=P.BC

1.	In an equilateral triangle ABC,AD is perpendicular to BC and AD²=P.BC² then find value of p
Answer» Since AD is height so AD=(√3)a/2 And BC is side of equilateral triangle? so BC=aNow, AD²=p×BC²(√3a/2)² =p×a²3a²/4 =p×a²P=3/4 P=3/4
