Answer -
In the given figure, ST isa straight line and ray QP stands on it.
тИ┤ тИаPQS + тИаPQR =180┬║ (Linear Pair)
тИаPQR = 180┬║ тИТ тИаPQS (1)
тИаPRT + тИаPRQ = 180┬║ (Linear Pair)
тИаPRQ = 180┬║ тИТ тИаPRT (2)
It isgiven that тИаPQR = тИаPRQ.
Equatingequations (1) and (2), we obtain
180┬║ тИТ тИаPQS = 180
┬атИТ тИаPRT
тИаPQS = тИаPRT
