Question

Please help!!!! Will givebrainly! No wrong answers. A statement and portions of the flowchart proof of the statement are shown.

Which reason should appear in the box labeled 1?


A. Ruler Postulate

B. Angle Addition Postulate

C. Angle Congruence Postulate

D. Linear Pair Postulate

Answer 1

Beacuse you are adding UVW to WVX, it would be: B. Angle Addition Postulate

Answer 2

Answer: B. Angle Addition Postulate

Step-by-step explanation:

• Angle addition postulate says that the measure of an angle produced by joining two angles is the sum of the measures of the two angles.

i.e. For a given angle ∠MNO if Q is interior of ∠MNO then ∠MNO=∠MNQ+∠QNO.

From the given figure, we can see that W lies in the interior of ∠UVX .

Then, ∠UVW+∠WVX=∠UVX which in box 1.

Thus, the reason should appear in the box labeled 1 =  Angle Addition Postulate

Hence,  the correct answer is option (B) "Angle Addition Postulate"  .
