In a parallelogram, opposite angles are equal and adjacent angles are supplementary.

1. Since one angle is 90°, the angle opposite to it will also be 90°. This is because in a parallelogram, opposite angles are equal.

2. The adjacent angles to the 90° angle will be supplementary to it. This means they will add up to 180°. So, if one angle is 90°, the angle next to it will be 180° - 90° = 90°.

3. Therefore, all the angles in the parallelogram will be 90°.

So, the measures of the other three angles in the parallelogram are 90°, 90°, and 90°.

2. The adjacent angles to the 90° angle will be supplementary to it. This means they will add up to 180°. So, if one angle is 90°, the angle next to it will be 180° - 90° = 90°.

3. Therefore, all the angles in the parallelogram will be 90°.

So, the measures of the other three angles in the parallelogram are 90°, 90°, and 90°.
