Question

13. Show that the sides 5 cm, 12 cm and 13 cm
make a right angled triangle. Find the
length of the altitude on the longest side.​

Answer 1

if 5cm, 12cm and 13cm will make a right angled triangle... then,. 13^2 = 12^2 + 5^2

169= 144+ 25

169=169

So it means 13cm, 12cm and 5 cm make a right angled triangle.

But I don't know the answer of 'find the length of the altitude on the longest side'.
