In parallelogram ABCD, one of the angles is 124 * find the other angles of the parallelogram.

1. It is known that opposite angles of a parallelogram are equal.

2. If, according to the problem statement, the angle B is equal to 124 *, then the angle D as its opposite is equal to 124 *.

3. Angles A and B are internal one-sided angles with parallel sides of the parallelogram AD and BC and the secant side AB, which means, by definition of such angles, angle A and angle B add up to 180 *.

Angle A + angle B = 180 *;

Angle A = 180 * – Angle B = 180 * – 124 * = 56 *.

Answer: Angle A is 56 *, angle B is 124 *, angle C is 56 *, angle D is 124 *
