Which statement is true about this argument? Premises:

If a quadrilateral is a square, then the quadrilateral has four right angles.

Quadrilateral JKLM has four right angles.

Conclusion:

Quadrilateral JKLM is a square.

The argument is not valid because the conclusion does not follow from the premises.

The argument is not valid because the premises are not true.

The argument is valid by the law of detachment.

The argument is valid by the law of syllogism.

The argument is valid by the law of detachment

Step-by-step explanation:

The law of detachment simply states that when the hypothesis is true, then the conclusion must also be true.

In this case, the argument is valid since the conclusion that "Quadrilateral JKLM is a square" follows from the argument that "a quadrilateral is a square, then the quadrilateral has four right angles".

The law of detachment is expressed here.

step-by-step explanation:

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.
