Question

Please help!!!!!!!!!!

Answer 1

By hypotenuse - side test (HL) the two triangles are congruent.

Explanation:

In ∆ABC and ∆DCB

i) angleABC = angleDCB.....(each 90°)

ii) BC = BC .....( common side)

iii) AC = DB.....(given)

therefore by hypo-side test ∆ABC congruent ∆DCB

Answer 2

HL

Explanation:

∠B ≅ ∠C = 90°

AC = DB {Given and they are hypotenuse}

BC = CB {Reflexive property}

ΔABC ≅ ΔDCB {HL congruent}
