Answer:
arc AC is congruent to arc BD
Step-by-step explanation:
By drawing the perpendicular CD we get some congruent triangles, first we have ΔACP = ΔADP.
Thus, since these two triangles are congruent, we have that their sides and angles are congruent.
So, AC = AD
But we also got the congruent triangles ΔCPB and ΔDPB, where we will have congruent angles and sides:
So, ∠PBC = ∠DBP = ∠DBA
Finally, we get the congruent triangles ΔABC and ΔABD where ∠BDA = ∠ACB
Thus the statement which is not true is that arc AC is congruent to arc BD
