From the data from the figure:
A) if $\angle CBD = 25^\circ$ , then $\triangle АВС \cong \triangle CDB$
B) if $АС \perp CD$, then $AB = CD$
C) if $AC||BD$, then $BC=AD$
D) $\triangle ABC \not\cong CDB$
I know that the correct answer is $D$ because the hypotenuse of $\triangle BCD$ is a cathetus in $\triangle ABC$. Therefore, $AC>BC$ and the triangles cannot be congruent. Assuming $A$ is the correct answer, we have $BC$ - common side, $\angle BDC=\angle ABC=90^\circ$ and $\angle CBD=\angle ACB=25^\circ$. We have one side and two angles. Isn't this the Angle-Angle-Side congruence?
