Question:-

☞ R ɪs ᴛʜᴇ ᴍɪᴅ ᴘᴏɪɴᴛ ᴏғ PQ ᴀɴᴅ Q ɪs ᴛʜᴇ ᴍɪᴅ ᴘᴏɪɴᴛ ᴏғ RS ᴠᴇʀɪғʏ ᴛʜᴀᴛ: PR=QS,RQ= QS, PR=RQ.

To Find:-

☞ Vᴇʀɪғʏ ᴛʜᴀᴛ: PR=QS,RQ= QS, PR=RQ

Given:-

☞ R ɪs ᴛʜᴇ ᴍɪᴅ ᴘᴏɪɴᴛ ᴏғ PR

Solution:-

PR = QS (1)

Aɢᴀɪɴ, R ɪs ᴛʜᴇ ᴍɪᴅ ᴘᴏɪɴᴛ ᴏғ QS

QR = PQ (2)

Nᴏᴡ, PR=QS,RQ= QS, PR=RQ

☞ PR = 3 QS [ Usɪɴɢ (1) ᴀɴᴅ (2) ]

☞ QS = 1/3 PS

Oɴ ᴘᴜᴛᴛɪɴɢ ᴠᴀʟᴜᴇ ᴏғ QS ɪɴ (1), Wᴇ ɢᴇᴛ :-

☞ PR = 1/3 PS

Given : R is the mid-point to PQ  

Q is the mid-point of RS.

To Find : Verify that PR = QS

Solution:

Let say PQ  = 2X

R is the mid-point to PQ  

=> PR = QR  = PQ/2

=> PR = QR  = 2X/2

=> PR = QR = X

Q is the mid-point of RS.

=> QR = QS = RS/2

QR = X

=> QS = RS/2 = X

=> QS = X

PR = QR = QS = X

=> PR = QS

QED

Hence proved
