Work Step by Step
The figure shows that the triangle I and the triangle II both contain equal sides and equal angles marked with one tick.
The angles that are opposite to the side marked with one tick in triangle I and triangle II form a pair of vertically opposite angles with equal measurement.
Since, the lengths of one side of triangle I is equal to the length of the corresponding side of triangle II and the measurement of two angles are also equal in triangle I and triangle II. Hence, the two triangles are congruent by ASA Condition.
Hence, the triangle I and the triangle II are congruent by ASA Condition.
