Given: \overline{AC} AC

and \overline{DB}

DB

bisect each other

Prove: \triangle ABE \cong \triangle CDE△ABE≅△CDE.

△ABD ≅ △CBD is below

Step-by-step explanation:

Given:

AD = CD      BD bisect AC

To Prove:

△ABD ≅ △CBD

Proof:

In  ΔABD  and ΔCBD  

BD ≅ BD              ……….{Reflexive Property}

∠ADB ≅ ∠CDB    …………..{Measure of each angle is 90°(  )}

AD ≅ CD              ……….{  }

ΔABD  ≅ ΔCBD   ….{By Side-Angle-Side Congruence test}  ...Proved

I think this is it? Hope it helps :)

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.
