1 similar parallelograms
EFGH and WXYZ
set up
2/3 = 6/x
solve for x
2/3 times x = 6
x = 6 divided by 2/3
x =9
2 similar pentagons
JKLMN and VWXTZ
similar shapes have the same angles
60 degrees
2. similar triangles
lance the alien
set up
5/8 = x/32
solve for x by multiplying 32 on both sides
(5/8) times 32 = x
x = 20
4 similar triangles
ADE and ABC
set up
x/2 = 12/(4+2)
x/2 = 12/6
x/2 = 2
x = 4
5 similar triangles
perimeter
two different set ups
first:
30/5 = (YZ)/6
6 = (YZ)/6
36 = YZ
second:
30/5 = (XZ)/10
6 = (XZ)/10
60 = XZ
perimeter
60 + 36 + 30 = 126
