Use the figure and flowchart proof to answer the question: Which theorem accurately completes Reason A? A. Alternate Interior Angles Theorem
B. Corresponding Angles Theorem
C. Alternate Exterior Angles Theorem
D. Same-Side Interior Angles Theorem

I believe that it would answer D) same side interior angles.

Same side interior angles or consecutive angle always add up to 180 degrees

A cannot be because the angles that the diagram is telling us are not alternate interior angles, alternate interior angles would be angle UQR and angle QRZ

B cannot be because they are not corresponding and also they are not Alternate Exterior angles. Which left us with D.

Hope this help!! :

step-by-step explanation:

7*1=7

7*2=14

7 is less than 21

14 is less than 21
