Question

What property justifies the following statement:

If angle N is approximately angle X and angle X is approximately angle C then angle N is approximately angle C

Answer 1

It seems like the transitive property, but that's a property of equality/congruency. I'm not entirely sure it holds for approximations, thought it seems like it should

Answer 2

Would this help?

Answer 3

yeah.
≅ is the congruent sign.
≈ is the approximate sign.
So that's the transitive property.

If A = B and B = C, then A = C

Answer 4

Oh ok I'm sorry lol thank you :)

Answer 5
