A parallelogram has 2 equal opposite acute angles and 2 equal opposite obtuse angles whereas all 4 angles add up to 360 degrees.
Not always. A parallelogram only has to have two equal parallel sides and its angles does not have to be 90°. Only two types of parallelogram, the rectangle and the square, have four right angles.
No. There are lots of different types of parallelograms, which have varied angles.
No. In a parallelogram, opposite angles are congruent.
There are no right angles in a parallelogram. A parallelogram only has right angles if it is a rectangle, in which case it has exactly four.
Opposite angles of a parallelogram are equal.

No. In a parallelogram, opposite angles are congruent.
There are no right angles in a parallelogram. A parallelogram only has right angles if it is a rectangle, in which case it has exactly four.
Except for rectangles, no parallelogram has right angles.
Opposite angles of a parallelogram are equal.
Yes, opposite angles of a parallelogram are congruent.
The Parallelogram Consecutive Angles Conjecture states that the consecutive angles in a parallelogram are supplementary. This means that the sum of two adjacent angles in a parallelogram is always 180 degrees. This property follows from the fact that opposite angles in a parallelogram are congruent.
A parallelogram has opposite sides parallel and equal in length, and opposite angles are equal. Squares, rectangles and rhombuses are all parallelograms.
Adjacent angles in a parallelogram are supplementary.
a parallelogram has two pairs of equal angles
