$\Delta XYZ$ was reflected over a vertical line, then dilated by a scale factor of $\frac{1}{2}$, resulting in $\Delta X'Y'Z'$. Which must be true of the two triangles? Select three options.

• $\Delta XYZ \sim \Delta X'Y'Z'$
  
• $\angle XZY \cong \angle X'Z'Y'$
  
• $\overline{YX} \cong \overline{Y'X'}$
  
• $XZ = 2X'Z'$
  
• $m\angle YXZ = 2m\angle Y'X'Z'$
