Answer 1

Hey mate here is your answer ⤵⤵⤵

In the fig. we can see that $\angle1=\angle2=90°$

Hence,$\angle1+\angle2=90°+90°=180°$

$\therefore AD||BC$ [because we know that if the sum of consecutive interior angles are supplementary I.e.180°,the lines are parallel ]

Answer 2

HERE WE ARE GIVEN THAT

1=2 = 90°


now in line AD AND BC AND TRANSVERSAL AB


1+2 = 90+90 = 180°

there for we know that IF ANGLES ON THE SAME SIDE OF TRANSVERSAL ARE SUPPLYMENTRY THE LINE ARE PARALLEL

HENCE

AD || BC
