Answer 1

Answer:

ΔABD is congruent to ΔCBD by RHS congruency.

Step-by-step explanation:

Given:

angle A = angle C they are right angles

AB = CB

To Prove:

ΔABD is congruent to ΔCBD

Proof:

In ΔABD and ΔCBD,

AB = CB [Given]

angle A = angle C [Right angles]

BD = BD [Common hypotenuse]

Therefore,

ΔABD is congruent to ΔCBD by RHS congruency.

Answer 2

Answer:

Down below!

Step-by-step explanation:

so for this we gotta use one of this guys!

SSS SAS AAS ( S= side of a triangle , A = angle of a trangle)

if two triangle has the same as one of these three properties,

those two triangles will be identical,

for, ΔABD and ΔCBD

so AB= CB ( 2 sides of two triangles are same)

now ∠A and ∠C are equal ( 2 angles of 2 triangles are same= right angles)

then for both triangles BD is common!

so we've proven that, this two tangles are identical (SAS, Side Angle Side)
