represent:
Angle
A
is obtuse.
Let
n
represent:
Angle
B
is obtuse.
Which is a symbolic representation of the following argument?
Angle

is obtuse if and only if Angle
B
is obtuse.
Angle
A
is obtuse or Angle

Example of the law of detachment:
Let
p
= “a dog eats bread”
Let
q
= “the dog gains weight”
p
→
q,
“If a dog eats bread, then the dog gains weight” is a true
statement.
John’s dog eats bread. What can be concluded?

Example of the law of contrapositive:
Let
p
= “a dog eats bread”
Let
q
= “the dog gains weight”
p
→
q
means “If a dog eats bread, then the dog gains weight.”
p
→
q
is a true statement.
What is the contrapositive of this statement? Is it a true
statement?

Example of the law of syllogism:
Let
p
= “a dog eats bread”
Let
q
= “the dog gains weight”
Let
r
= “the dog gets fat”
p
→
q
means “If a dog eats bread, then the dog gains weight.”
q
→
r
means “If the dog gains weight, then the dog gets fat.”
Using the law of syllogism, what is the logical conclusion?

Example of a counterexample:
Let
p
= “
n
is an integer and
n
² is divisible by 4”
Let
q
=
“n
is divisible by 4”
p
→
q
means “If
n
is an integer and
n
² is divisible by 4, then
n
is
divisible by 4.”
A
counterexample
is any example that will prove a statement
false. In this case, a number for which
p
is true and
q
is false is
a counterexample.
