Geometry... Please help and I'll mark brainliest. Triangle proofs & reasons

We are given that,

Polygons ABC and DBC are triangles.

Also, ABC and DBC are Right Triangles as ∠ABC and ∠DBC are 90 respectively.

AB ↔ CD

Now,

From the HL Congruency we know that,

"Two Right triangles are congruent if the Hypotenuses and at least One Side of both the triangles correspond to each other."

Here,

Here, As the three conditions of being congruent through HL Congruency are satisfied, ΔABC &  Δ DBC are congruent through the HL Congruency Criterion.

ΔABC ≅ Δ DBC [Hence, Proved]
