Which statement is used to prove that angle abd is congruent to angle acd?
in the figure below, segment ac is congruent to segment ab.
which statement is used to prove that angle abd is congruent to angle acd?
segment ad bisects angle cab.
triangle acd is similar to triangle abd.
segment ad is congruent to segment ac.
angle cab is congruent to angle cba.

Answer with explanation:

In Δ A CD and Δ A B D

   AC ≅ AB⇒⇒⇒[Given]

 Side,AD is Common.

You can prove two triangles Congruent either by S AS, or SSS.

So,either,→ BD=CD

or, →∠CAD=∠BAD

Δ A CD≅   Δ A B D⇒⇒⇒[S A S]

Option 1: Segment AD bisects angle CAB.

is true.

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
