Question

Kim is designing a railway track. Each point on the railway track should be equidistant from the two roads shown below.



Kim wrote the following steps to construct the railway track.

Step
Description
1
Adjust the compass to a medium width and place it at point B and draw an arc which cuts at point P and at point Q.
2
Adjust the compass to the width of and place it at point P and cut an arc.
3
Reduce the width of the compass and place it at point Q and draw an arc which intersects the previous arc at a point S.
4
Use a straightedge to connect the points B and S and extend i

Answer 1

Which is the first step that was done incorrectly?

Step 1, because the compass should be placed at points A and D.

Step 4, because the compass should be used to connect the points B and S.


Step 3, because the width of the compass should not be changed.

Step 2, because the width of the compass should not be so large.

Answer 2

Answer 7

Nigel read the following statements.

Statement 1: If two lines intersect, then they intersect in exactly one point.
Statement 2: If two distinct planes intersect, then they intersect in exactly one line.

Which of these options is correct?

Statement 1 and Statement 2 represent theorems.

Statement 1 represents a postulate and Statement 2 represents a definition.



Statement 1 and Statement 2 represent postulates.

Statement 1 represents a definition and Statement 2 represents a theorem.
