In right triangle ABC, what is the length of altitude drawn from the vertex A to BC?

Answer»

In this right angled triangle ΔABC, length of the altitude drawn from vertex A is the leg AB itself. By Pythagoras theorem.

AC² = AB² + BC²

13² = AB² + 12²

169 = AB² + 144

AB² = 169 – 144 = 25

AB² = 52

AB = 5cm
