Hi,

I just want to clear a doubt I have. Can we use similar triangles formula on non right angled triangles as well or does it only apply to right angled triangles?

There was a question with a square based pyramid, and it was a related rates question about the rate of change of volume of water in the pryamid and water depth in it.

The triangle on the pyramid is not a right angled triangle. So I was wondering whether I can use the similar triangle formula to equate the height & base of the pyramid?

Thank you so much in advance!!
