Answer:
The slope of ZW is
The lenght of ZY is
Quadrilateral WXYZ is a square
Step-by-step explanation:
<u>Statements</u>
<u>case A)</u> The slope of ZW is
The statement is True
we know that
The formula to calculate the slope between two points is equal to
we have
substitute
<u>case B)</u> The slope of YX is
The statement is False
we know that
The formula to calculate the slope between two points is equal to
we have
substitute
<u>case C) </u>The lenght of ZY is
The statement is True
we know that
the formula to calculate the distance between two points is equal to
we have
substitute
<u>case D) </u>The lenght of WX is
The statement is False
we know that
the formula to calculate the distance between two points is equal to
we have
substitute
<u>case E)</u> Quadrilateral WXYZ is a square
The statement is True
Because sides ZW and YX are parallel sides (has the same slope)
<u>Slope ZY </u>
we have
so
ZW and ZY are perpendicular sides (the product of their slopes is equal to minus one)
<u>Slope WX</u>
we have
ZY and WX are parallel sides (has the same slope)
<u>distance ZW</u>
we have
<u>distance YX</u>
we have
The four sides are congruent
case F)
The statement is False
----> is not correct
the value of YZ is
