Answer
\[\Delta \text{I}\cong \Delta \text{II}\]by SAS or RHS Condition.
Work Step by Step
The figure shows that the triangle I and the triangle II both contain equal angles of \[{{90}^{\circ }}\] each marked with square.
Both triangles also contain equal sides marked with one tick and two ticks.
Since the lengths of two sides of triangle I are equal to the lengths of the corresponding sides of triangle II and the measurement of the angles (\[{{90}^{\circ }}\]) are also equal in triangle I and triangle II, hence the two triangles are congruent by SAS Condition.
Hence\[\Delta \text{I}\]and \[\Delta \text{II}\] are congruent by SAS or RHS Condition.
