For the given true statements, what can you conclude using the Law of Syllogism? If a quadrilateral is a square, then it has four right angles. If a quadrilateral has four right angles, then it is a rectangle. If a quadrilateral is a rectangle, then it has four right angles.
If a quadrilateral is a square, then it is a rectangle.
If a rectangle is a quadrilateral, then it has four right angles.
If a quadrilateral has four right angles, then it is a square.

d.192

step-by-step explanation:

12*16=192

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
