Answer:
(C) ASA method
Step-by-step explanation:
Given: From the figure, it can be seen that ∠BAC=∠CDE=25° and AC=CD.
To find: Method to prove two triangles are congruent.
Solution: From the figure, it can be seen that ∠BAC=∠CDE=25° and AC=CD, therefore
From ΔABC and ΔCDE, we have
∠BAC=∠CDE=25° (Given)
AC=CD (Given)
∠ACB=∠DCE (Vertically opposite angles)
thus, by ASA rule,
ΔABC ≅ΔCDE
Hence, option C is correct that is by ASA method.
