For the following argument, which statement is a premise?

argument:
any three points that are noncollinear define a plane.
points p, q, and r are noncollinear.
therefore, points p, q, and r define a plane.

any two points define a line.

points p, q, and r are noncollinear.

points p, q, and r define a plane.

every plane is flat. for the following argument, which statement is a premise?

points p, q, and r define a plane.

every plane is flat.

question 2 which of the following conclusions completes the syllogism?

premise 1: if you bisect an angle, then the two resulting angles will be congruent.
premise 2: if the two resulting angles are congruent, then they will have equal
measure.
conclusion:

if the two angles have equal measure, then you bisected an angle.

if two angles are congruent, then an angle has been bisected.

if you bisect an angle, then the two resulting angles will have equal measure.

if you bisect an angle, then you will get two resulting angles.

question 3. which statement about the following argument is true?

argument:
if you do not get enough sleep, you will be tired.
you did not get enough sleep.
you will be tired.

the argument is valid by the law of syllogism.

the argument is valid by the law of detachment.

the argument is invalid.

the argument is valid, but does not follow the law of syllogism or the law of detachment.

question 4. which statement is true about the following argument?

argument:
if two lines are perpendicular, then they intersect to form right angles.
lines ab and cd intersect to form right angles.
therefore, lines ab and cd are perpendicular.

the conclusion is true, but the argument is not valid.

the conclusion is false, and the argument is not valid.

the conclusion is true, and the argument is valid by the law of syllogism.

the conclusion is true, and the argument is valid by the law of detachment.

question 5. which statement about the following argument is true?

argument:
if you have a job, then you have an income.
if you have an income, then you must pay taxes.
therefore, if you have a job, then you must pay taxes.

the argument is valid by the law of syllogism.

the argument is valid by the law of detachment.

the argument is invalid.

the argument is valid but does not follow the law of syllogism or the law of detachment.

1) For the following argument, which statement is a premise?

Argument:
Any three points that are noncollinear define a plane.--> this is a premise
Points P, Q, and R are noncollinear.---> this is a premise
Therefore, points P, Q, and R define a plane.---> this is the conclusion (if the two premises are true the conclusion is true)

Any two points define a line.--> no (it is not in the argument)

Points P, Q, and R are noncollinear.---> yes, this is the righ choice

Points P, Q, and R define a plane.---> no (this is the conclusion)

Every plane is flat. ---> no (it is not in the argument)

.

Question 2 Which of the following conclusions completes the syllogism?

Premise 1: If you bisect an angle, then the two resulting angles will be congruent.
Premise 2: If the two resulting angles are congruent, then they will have equal
measure.
Conclusion:

If the two angles have equal measure, then you bisected an angle.

If two angles are congruent, then an angle has been bisected.

If you bisect an angle, then the two resulting angles will have equal measure.---> this is the right choice (by using a transitiive argument p->q, q ->r, then p -> r, this is the law of syllogism)

If you bisect an angle, then you will get two resulting angles.

Question 3. Which statement about the following argument is true?

Argument:
If you do not get enough sleep, you will be tired.
You did not get enough sleep.
You will be tired.

The argument is valid by the Law of Syllogism.

The argument is valid by the Law of Detachment. ---> this is the right choice. The law of detachment allows to separate the hypothesis from the conclusion: this is the definitionof the law: if you know that  p and also p -> q are true, then you can conclude q.

The argument is invalid.

The argument is valid, but does not follow the Law of Syllogism or the Law of Detachment.

Question 4. Which statement is true about the following argument?

Argument:
If two lines are perpendicular, then they intersect to form right angles.
Lines AB and CD intersect to form right angles.
Therefore, lines AB and CD are perpendicular.

The conclusion is true, but the argument is not valid.-> this is the right choice. The conclusion cannot be extracted from the argument because p->q allows to conclude q given p, not conclude p given q. 

The conclusion is false, and the argument is not valid.

The conclusion is true, and the argument is valid by the Law of Syllogism.

The conclusion is true, and the argument is valid by the Law of Detachment.

Question 5. Which statement about the following argument is true?

Argument:
If you have a job, then you have an income.
If you have an income, then you must pay taxes.
Therefore, if you have a job, then you must pay taxes.

The argument is valid by the Law of Syllogism.-> this is the right choice the law of syllogism states p->q, q->r, then p->r

The argument is valid by the Law of Detachment.

The argument is invalid.

The argument is valid but does not follow the Law of Syllogism or the Law of Detachment.
