Directions Identify the hypothesis and the
conclusion of each conditional. 1. If three
points form the vertices of a triangle, then they
lie in the same plane. 2. Four angles are formed
if two lines intersect.

Directions Determine if each conditional is
true. If false, then give a counterexample. 3. If
x2 25, then x 5.
Directions Does each conditional use inductive
or deductive reasoning? 4. Two angles that form a
linear pair are supplementary. One of the
angles measures 60o . One would conclude that
the other angle is 120o .
