Two triangles are similar but not congruent if they have three congruent angles but the side lengths are not equal.
What is the congruency of triangles?
To show how can the triangles be proven similar by the SSS similarity theorem:
The two triangles can be shown to be similar given that the ratios of the corresponding sides ΔWUV and ΔYXZ are constant
Reason:
Known parameters are:
ΔWUV and ΔXZY are shown:
∠VUW ≅ ∠YXZ
∠UWV ≅ ∠XZY
∠UVW ≅ ∠ZYX
Length of side VW = 60
Length of side VU = 50
Length of side UW = 40
Length of side ZY = 48
Length of side YX = 40
Length of side XZ = 32
The ratio of the sides are:
[tex]\frac{VW}{ZY} =\frac{60}{48} =\frac{5}{4} \\\frac{VU}{YX} =\frac{50}{40} =\frac{5}{4} \\\frac{UW}{XZ} =\frac{40}{32} =\frac{5}{4}[/tex]
Therefore, given that the angles of ΔWUV and ΔXZY are all congruent, and the sides of triangle ΔWUV and ΔXZY have a constant proportion, we have that the two triangles are congruent by the Side-Side-Side SSS congruency theorem, and we have:
ΔWUV ~ ΔYXZ given that ΔYXZ is a scaled drawing of ΔWUV.
