2.Given:PR=~QS. Is PQ=~ RS and why?​

Answer»

ANSWER:

PQ =~ RS

Step-by-step explanation:

PR =~ PQ + QR

QS =~ QR + RS

You will notice the BOTHTHE equations have QR common.

We also KNOW that PR =~ QS.

Thus, equating the FIRST two equations,

PQ + QR =~ QR + RS

cancelling QR on both sides

PQ =~ RS
