you stated the converses , but nothing about true/false
1. picture football goalposts as a vertical plane
... the side posts are vertical , the crossbar is not
2. (-7)^2 = 49
So the directions say:
Provide a counterexample to show that each statement is false.
You can use words or make a diagram.
These are the two questions that I'm stuck on:
1. If a line lies in a vertical plane, then the line is vertical
2. If x^2=49, then x=7
I think that the answer to them is this, but I just wanted some verification:
1. If a line is vertical, then the line lies in a vertical plane.
2. x=7 if x^2=49
