3. Which choice shows a true conditional, with the hypothesis and conclusion identified correctly? A. If two lines intersect at right angles, then the two lines are perpendicular.
Hypothesis: Two lines are perpendicular.
(**Hint you can re-write the
Conclusion: Two lines intersect at right angles.
conditional in if-then form)
B. If two lines intersect at right angles, then the two lines are perpendicular.
Hypothesis: Two lines are perpendicular.
Conclusion: Two lines do not intersect at right angles.
C. Two lines are perpendicular if the lines intersect at right angles.
Hypothesis: Two lines intersect at right angles.
Conclusion: Two lines are perpendicular.
D. Two lines are parallel if the lines intersect at right angles.
Hypothesis: Two lines intersect at right angles.
Conclusion: Two lines are parallel.
