The measure of segment PQ with P (-4.-9) and Q (4 -3) is 10 units.
<h3>How to find the length of a Line segment?</h3>
The formula for the length of the line segment is;
d = √[(x2 − x1)² + (y2 − y1)²]
We are given the coordinates of Line segment PQ as;
P (-4.-9) and Q (4 -3)
Thus, distance of line segment PQ is;
d = √[(4 − (-4))² + (-3 − (-9))²]
d = √(64 + 36)
d = √100
d = 10
Thus, we can say that the measure of segment PQ with P (-4.-9) and Q (4 -3) is 10 units.

<h3>What is similarity?</h3>
Two objects are similar if they have the same shape, or one has the same shape as the mirror image of the other.
Given:
Using theorem
If two triangles are similar, then the ratio of the area of both triangles is proportional to the square of the ratio of their corresponding sides.
ΔSDF/Δ RTY = (SD/RT)= (DF/TY)= (FS/ YR)
ar ΔSDF² / ar ΔRTY² = 16/81
SD/ RT = 4/9
SD = 4x, RT= 9x
SD= 8
4x = 8
x = 2
So,
RT= 9*2 = 18
SF = RT -2
SF = 16
(SD/RT)= (FS/ YR)
8 / 18 = 16/ YR
YR= 36
TY= 9 +RY = 45
(DF/TY)= (FS/ YR)
DF / 45= 16/ 36
DF=20
