Sagot :
With this question we use the properties of the figures to solve
Rectangle and square have their sides being perpendicular to each other whiles rhombus and parallelogram aren’t
Also square and rhombus have their sides to be equal and opposite sides perpendicular but parallelogram and rectangle have opposite side only equal and perpendicular
Taking Q 15
W(-4,2) , X(-2,4) ,Y(0,2) and Z(-2,0)
First checking whether all sides are the same
Length of line
= √[(y2-y1)2 +(x2-x1)2]
WX= √[(4-2)2 +(-2- -4)2]
WX= √[(2)2 +(2)2]
WX= √[(4 +4)] = √8 =2 √2 units
XY = √[(2-4)2 +(0- -2)2]
XY = √[(-4)2 +(2)2] = √(16+4)
= √20 = 2 √5 units
WY = √[(2-2)2 +(0- -4)2]
WY = √16 = 4 units
Since 3 sides hv been calculated not to be equal then is none of them
Use these steps to know the others
Hope this helped

Step-by-step explanation:
yes there is a distance formula
[tex]distance = \sqrt{ {(x1 - x2)}^{2} + {(y1 - y2)}^{2} } [/tex]
let me do 15th question, in this i take distance between Point W(-4,2)and X(-2,4)
WX=√[(-4 - -2)² +(2-4)²]
WX= √[(-2)²+(-2)²]
WX= √4+4
WX=√8
Similarly find XY ,YZ ,ZW you will get
XY= √8
YZ=√8
ZW=√8
ALL SIDES ARE EQUAL THAT MEANS ITS SQUARE
ALL SQUARES ARE RECTANGLE BECAUSE ITS HAVE PARALLEL SIDES AND ANGLES ARE 90°
ALL SQUARES ARE RHOMBUS BECAUSE ALL SIDES ARE EQUAL
ALL SQUARES ARE PARALLELOGRAM BECAUSE ALL SIDES ARE PARALLEL
so in this question it will be parallelogram, square, rectangle , RHOMBUS
Hope u do the same thing in 17 , 18 and 19
