If in two right triangles the hypotenuse and one side of one triangle are equal to the hypotenuse and one side of the other triangle, then the two triangles are congruent. This is Known as RHS Congruency.
For given two right angle triangles, hypotenuse AC = hypotenuse XZ , BC = YZ and \(\angle\) B = \(\angle\) Y, then using RHS rule, \(\Delta\) ABC ≅ \(\Delta\) XYZ.
