1. A logic statement written in if-then form.
A conditional statement such as: If I get paid today,
then I'll take you to the movies.
If p, then q.
The 'If' part of a conditional statement.
Represented with the letter p
The 'then' part of a conditional statement.
Represented with the letter q
When you give the opposite of a statement by adding
the word 'not'.
Represented with a single wavy line (~)
~p is read as 'not p'

2. The converse of a conditional statement is formed by
switching the hypothesis and conclusion.
If q, then p.
The inverse is formed by negating the hypothesis and
conclusion of a conditional statement. If ~p, then ~q.
The contrapositive of a conditional statement is formed by
negating and reversing the order of the hypothesis and conclusion. If ~q, then ~p.
Two statements that are either both true, or both false.
Coplanar lines that form right angles.
A statement formed with equivalent statements, where they're
separated with the phrase 'if and only if'.

3. The hypothesis is generally written first, followed by the conclusion.
an animal is a vertibrate it has a backbone

4. If a figure is a triangle,
then it has 3 sides.
If x = 2, then x2 = 4.

5. The conditional statement and contrapositive will ALWAYS
have the same truth value.
The converse and inverse will
ALWAYS have the same truth
value.
If you are an Olympian, then you are an
athlete. True, Olympians are athletes.
If you are an athlete, then you are an
Olympian. False, not all athletes are Olympians.

can still be an athlete.
If you are not an athlete, then you are
not an Olympian. True, a person who is not an athlete
cannot be an Olympian.

9. Conditional: If a figure is a square, then the figure is a rectangle
Conditional: If a figure is a square, then the figure is a rectangle. TRUE
Converse: If a figure is a rectangle, then the figure a square. FALSE
Inverse: If a figure is not a square, then the figure is not a square. FALSE
Contrapositive: If a figure is not a rectangle, then the figure is not a square. TRUE

10. A) True. They're a linear pair, which is supplementary.\
B) False. There's not enough info to say GJ is
perpendicular to HK.
