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.
Conclusion: Two lines intersect at right angles.
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 parallel if the lines intersect at right angles.
Hypothesis: Two lines intersect at right angles.
Conclusion: Two lines are parallel.
D:
Two lines are perpendicular if the lines intersect at right angles.
Hypothesis: Two lines intersect at right angles.
Conclusion: Two lines are perpendicular.
