plz tell me the solution​

Answer 1

Answer:

Step-by-step explanation:

Here is ur answer for the third question dear..

Given,

Bisectors of angle PQR & angle PRS meet at point T.

To prove,

angleQTR=1/2 angle QPR.

Proof,

<TRS = <TQR+<QTR

exterior angle of a triangle equals to the sum of the two interior angles.

<QTR =2 <TRS - 2<TQR------------(i)

<SRP = <QPR +<PQR

2<TRS = <QPR+2 <TQR

TR is a bisector of <SRP & QT is a bisector of <PQR

<QPR=2 <TRS - 2 <TQR

<QPR =2 (<TRS - <TQR)

1/2 <QTR= TRS - <TQR -------------(ii)

Equating (i) and (ii)

<QTR=1/2 <QPR

Hence proved....
