1. Triangle #1
a = 8
b = 15
c = 18
Triangle #2:
d = 10
e = ?
f = ?.
a/d = b/e = c/f = 8/10
15/e = 8/10
e = 18.75
18/f = 8/10
f = 22.5
2. Scale Factor=5/4 = 15/12=25/20 = 1.25
3. x/r = y/p = z/n. 👍

1. 15/x = 8/10 = 18/y
15/x = 4/5; 4/5 = 18/y
4x = 75 ; 4y = 90
x= 18.75 ; y = 22.5
2. 4/5 , 12/15 , 20/25
Scale factor = 4/5 or
Perimeter ∆1/ Perimeter ∆2 = 4+12+20/5+12+25 = 36/45 = 4/5
 The ratio of the perimeter of these two triangles is equal to the scale factor.
3. X/R = Y/P = Z/N 👍
