Question

plz solve question number

Answer 1

$\huge \boxed{ \mathbb{ \ulcorner ANSWER: \urcorner}}$


$\huge \bf \sf{ Given:-)}$


$\bf = > \angle1 = 90°.$


$\bf = > \angle2 = 90°.$




$\huge \sf{To \: Justify :-)}$



$\bf = > {AD || BC.}$



▶ Now,


→ Add angle 1 and angle 2.


$\bf = > \angle1 + \angle2 = 180°.$


➡ By Co - interior angles AB || CD.


✔✔ Hence, it is justified ✅✅.

Answer 2

$\huge \bf{hey}$


$\huge{ \mathfrak{here \: is \: answer}}$


$\bf{given - }$

$\bf{ \angle{1} = \angle{2} = 90 \degree}$

$\bf{to \: prove}$

$\bf{ad \parallel \: bc}$


in quardilateral ABCD


$\sf{add \angle \: 1 \: and \angle \: 2}$


90°+90°=180°

$\mathfrak{by \: co - interrior \: angle}$

it is proved that

$\huge{ad \parallel \: bc}$

$\huge \boxed{hope \: it \: helps}$
