Question

Would this be correct??

Answer 1

It already shares RT as a side, so to be SAS it just needs another shared side and angle, so I chose B. Just wanted to make sure if it was correct

Answer 2

SAS ==> Side-Angle-Side (The angle should be included between the two sides)

VRT and STR share the same side RT
VR is parallel to ST (given). That means angle VRT = angle RTS (interior alternate angles)
To apply SAS we need to have a side that includes the above angle between that side and the shared side RT. So VR must equal ST to apply SAS.
