<h3>Answer:</h3>
A. If two lines intersect and form right angles, they intersect and form 90° angles.
<h3>Explanation:</h3>
The first conditional can be described by ...
... if p then q
where
- p = two lines intersect and form right angles
- q = the lines are perpendicular
The second conditional can be described by ...
... if q then r
where
- r = they intersect and form 90° angles.
___
The Law of Syllogism tells us that we can conclude ...
... if p then r
where p and r are as defined above. This translates to ...
... If two lines intersect and form right angles, then they intersect and form 90° angles. (matches selection A)
