The given points are
W = -5
X = -2
Y = 1
Z = 4
We will plot them on the number line
Let us find the distance of the given segments
XY = 1 - (-2) = 1 + 2 = 3 units
ZW = 4 - (-5) = 4 + 5 = 9 units
16.
Since XY = 3 and ZW = 9, then
XY and ZW are not congruent segments
ZX = 4 - (-2) = 4 + 2 = 6 units
WY = 1- (-5) = 1 + 5) = 6
17. Since ZX = WY = 6 units, then
ZX and WY are congruent segments
YZ = 4 - 1 = 3 units
YX = 1 - (-2) = 1 + 2 = 3 units
18.
Since YZ = YX = 3 units, then
YZ and YX are congruent segments
