10. ID Hypothesis & Conclusion
In a plane, if lines l and m are equidistant from line p, then l || m.
Hypothesis = if lines l and m are equidistant from line p
Conclusion = then l || m

11. Truth value, converse, inverse, contrapositive.
Points X, Y and Z determine two lines.
False
Converse: Two lines determine points X, Y and Z.
Inverse: If there are not the points X, Y, and Z then they don’t determine two lines.
Contrapositive: If you don’t have two lines then they don’t determine points X, Y, and Z.
