Find the angles of the parallelogram if one of them is 36 degrees less than the other.
May 2, 2021 | education
| A parallelogram is a quadrangle whose sides are parallel in pairs.
Parallelogram angles properties:
Opposite angles are equal.
The sum of adjacent angles is 180 °. (Internal one-sided corners at the intersection of two parallel secant lines).
If the parallelogram is ABCD, then angle A + Angle B = 180 °, angle A is 36 ° greater than angle B, so angle A is angle B = 36 °.
angle A + angle B = 180 °
angle A – angle B = 36о
We add these equalities, the right side with the right, the left with the left.
angle A + angle B + angle A – angle B = 180 ° + 36 °.
Lodge B – will be mutually destroyed.
2 * angle A = 216о;
Angle A = 216 °: 2 = 108 °.
108о – angle В = 36о;
angle В = 108о – 36о = 72о.
Answer: 72o, 108o.
