are all the angles in a parallelogram equal

No, not all the angles in a parallelogram are equal. In a parallelogram, opposite angles are equal, but consecutive angles (angles next to each other) are supplementary, meaning they add up to 180 degrees. Specifically:

- If \(\angle A\) and \(\angle C\) are opposite angles, then \(\angle A = \angle C\).
- Similarly, if \(\angle B\) and \(\angle D\) are opposite angles, then \(\angle B = \angle D\).
- However, \(\angle A + \angle B = 180^\circ\) (and the same goes for \(\angle C + \angle D = 180^\circ\)).

This means that while opposite angles are equal, the adjacent angles are not necessarily equal to each other.
