▶⏩ Let the given angle = angle A= 80°.

=> We know that:-)

↪➡ The sum of adjacent angles of parallelogram is 180°.

↪➡ angle A + angle B = 180°.

↪➡ 80° + angle B = 180°.

↪➡ angle B = 180° - 80°.

↪➡ angle B = 100°.

=> We know that:-)

↪➡ Opposite angles of parallelogram are equal.

↪➡ angle A = angle C.

↪➡ angle C = 80°.

▶⏩ Now,

↪➡ angle B = angle D.

↪➡ angle D = 100°.

✔✔ Hence, all angles are :-)

=> angle A = 80°.✅✅

=> angle B = 100°.✅✅

=> angle C = 80°.✅✅

=> angle D = 100°.✅✅
