Question

From the figure and statement provided, select the proper TO PROVE statement.



If two parallel planes are cut by a third plane, the lines of intersection are parallel.

AB + BC = AC
MN = AB
a is parallel to b
AB = BC
m is parallel to l

Answer 1

Answer:

Step-by-step explanation:

As the given statement is that the lines of intersection are parallel. So, To prove statement must be to prove the two lines are parallel.

By using the same fact, statement 1 , 2 and 4 can be rejected as all thee three statement do not relate to parallel lines in any sense.

Now, it is also given that the lines of intersection are parallel but as we can see in the diagram the lines of intersection are a and b, So, it also contradicts statement 3.

Therefore, The correct TO PROVE statement is " a is parallel to b.
