Option D:
p, because ∠ABC
∠EDC.
Solution:
In ΔABC and ΔDCE,
Vertically opposite angles are congruent.
∠ACB ≅ ∠DCE
∠ABC ≅ ∠EDC
we cannot proceed further,
So ΔABC and ΔDC are not congruent triangles.
By this, Option A, Option B and Option C are false.
In ΔABC and ΔEDC,
Vertically opposite angles are congruent.
∠ACB ≅ ∠DCE (Angle)
∠ABC ≅ ∠EDC (Angle)
By AA similarity ΔACB and ΔDCE similar triangles.
Corresponding parts of similar triangles are congruent.
∠CED = ∠BAC
∠CED = p
Hence option D is the correct answer.
p, because ∠ABC
∠EDC.
