Question

In Don's congruence flowchart for problem 6-29, one of the ovals "AB/FD= 1". In Phil's flowchart, one of the ovals said, "AB=FD". Discuss with with your team whether these ovals say the same thing. Can equality statements like Phil's always be used in congruence flowcharts?​

Answer 1

Yes, they are saying the same thing. In fact, if a ratio equals one, it means that numerator and denominator are equal.

This is the reason why you can always use A=B or A/B, as they are totally equivalent.
