Answer
The figure shows that the triangle I and the triangle II both contain equal sides marked with one tick and two ticks.
The angles that are opposite to the side marked with two tick in triangle I and triangle II are equal to each other as the angles that are opposite to equal sides are equal in measurement.
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 are also equal in triangle I and triangle II. Hence, the two triangles are congruent by SAS Condition.
Hence, the triangle I and the triangle II are congruent by SAS Condition.
