Answer:
The correct option is 2. According to ASA postulate the triangle ABC and triangle EDC are congruent.
Step-by-step explanation:
From the given figure it is noticed that the triangle ABC and EDC are right angle triangles. The sides BC and CD are equal. The measure of angle B is 90 and the measure of D is 90.
[tex]\angle B\cong \angle D=90^{\circ}[/tex]
[tex]BC\cong DC[/tex] (Given)
[tex]\angle ACB\cong \angle ECD[/tex] (Opposite angles are same)
So by ASA postulate the triangle ABC and triangle EDC are congruent.
Therefore correct option 2 is correct.
