Please help to prove parallelogram.​
tino4ka555 [31]

The question requests proof that WV = VR. See the definition of Mathematical proof and the explanation for the proof below.

<h3>What is a mathematical proof?</h3>

Mathematical proof refers to the steps of logical arguments which are given to show that a mathematical statement is true or correct.

<h3>What is the proof that WV = VR?</h3>

  • Note that SR ║ QT;

Reason: This is given. The image is a parallelogram.

  • Hence, ∠PSR  = ∠WVP
    Reason: Alternate angles formed by two parallel lines crossing each other
Hence, SV = PVReason: This is given by the annotation on the image
  • Therefore: ΔSVR ≅ PVW
  • Reason: They are formed by two parallel lines crossing each other.

Therefore if  ΔSVR ≅ PVW;

Then WV = VR.
