Question

. EFGH is a parallelogam. if angle E=80, find the measure other three angles.​

Answer 1

Answer:

<A = 80°

<B = 100°

<C = 80°

<D= 100°

Step-by-step explanation:

▶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°

Answer 2

Answer:

80,100

Step-by-step explanation:

angle e=80

the opposite angles in a parallelogram are equal

so if angle e=80 g=80

now g=80 so the adjacent angles in a parallelogram is =180 so angle f=180-80=100 degrees

so if f=100 then h=100

check:total angle sum =360

e+f+g+h=360

80+100+80+100=360
