A black hole is a region of spacetime where gravity is so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.

Step-by-step explanation:
AB and CD bisect each other at O i.e, AO=BO and CO=DO
in ΔCOA and ΔDOB
Given CO=OD,∠COA=∠BOD [ vertically opp angles]
AD=BD
∴ΔCOA≅ΔBOD
(i) ∴AC=BD[C.P.CT]
