What is the next logical statement in the proof below?
given: M is the midpoint of AB
prove:2(AM) = AB
a) AM+AM=AB
b) AM=AB-MB
c) AB=AM+MB
d) M (A+B)=AB

Respuesta :

First, we have write down, in the language of mathematics that M is the midpoint of AB. This means that AB will have two parts, each of them ending with (or beginning with) M. This is how we do it: 

c) AB=AM+MB
The correct answer is AM+AM=AB I know what test this is.
