Similar triangles
The triangles ABC and XYZ are similar. Find the missing lengths of the sides of the triangles.
a) a = 5 cm b = 8 cm
x = 7.5 cm z = 9 cm
b) a = 9 cm c = 12 cm
y = 10 cm z = 8 cm
c) b = 4 cm c = 8 cm
x = 4.5 cm z = 6 cm
a) a = 5 cm b = 8 cm
x = 7.5 cm z = 9 cm
b) a = 9 cm c = 12 cm
y = 10 cm z = 8 cm
c) b = 4 cm c = 8 cm
x = 4.5 cm z = 6 cm
