Conditionals
A \"conditional statement\" is a statement that
can be expressed in the form \"if...then\".
Hypothesis:
This is the part of the sentence that follows the word \"If.... ,\"
Conclusion:
This is the part of the sentence that follows the word \"then ... .\"

A \"conditional statement\" is a statement that
can be expressed in the form \"if...then\".
Rewrite each of the following in conditional form.
Each angle of an equilateral triangle is 60°.
If each angle in a triangle is 60° then you have an equilateral triangle.
Biconditonal
If a triangle is an equilateral triangle then each angle must equal to 60°.
Parallel lines do not intersect.
Inscribed angles in a circle subtended by the same
arc are congruent.
