WebWe know the ratio is 3:1, so since 3 + 1 equals 4, we want to divide these numbers into four parts. 16 divided into four parts is 4. And 4 divided into four parts is 1. We want the line AB to have 3 of the parts and the line BC to have one of the parts. That will make the line AB to be three times as long as BC. So if we start at point C, we ...
