The letters for XYZ are in the wrong order.
The correct statement should be ΔTUV ≅ Δ XYZ
When creating congruence assertions, the sequence of the letters is important.
The assertion is that ΔTUV ≅ Δ XYZ
In that order, the first two letters of each are "TU" and "XY".
However, TU has a single tickmark, but XY has a double tickmark. The two sides are firmly opposed.
Instead, the statement should read: ΔTUV ≅ Δ XYZ because of the three following facts:
ZY (single tickmark) = TU
UV = YX (tickmark twice)
ZX (triple tickmark) = TV
Take note of the following:
TUV and ZYX's first two letters are TU and ZY.
TUV and ZYX's final two letters are UV and YX.
TUV and ZYX's first and third letters are TV and ZX.
