Question

Please answer me fast frnds .​

Answer 1

Step-by-step explanation:

Here,

1. angle PQR= angle PRQ [Given]

2.angle PQS= 180°- angle PQR [ Being supplementary angle]

3. angle PRT=180° - angle PRQ [ Being supplementary angle]

4. angle PRT = 180° - angle PQR

[ From St. no 1]

5. angle PQS = angle PRT [ From st. no 2 and 4]

Answer 2

Answer:

let us consider

angle PQR be 1

angle PRQ be 2

angle PQS be 3

angle PRT be 4

it is given that 1=2.........(#)

by linear pair--

1+3=180°. (1)

2+4=180°. (2)

equating (1) and (2).....

1+3=2+4......(4)

putting value of (#) in equation (4)

1+3=1+4

1 is cancelled by 1

therefore, 3=4

=PQS=PRT

hence proved
