To determine which statement is not always true about a parallelogram, we should first understand the properties of a parallelogram.
1. Opposite sides are parallel:
This statement is always true for any parallelogram. If the sides are not parallel, the shape cannot be a parallelogram.
2. Opposite sides are equal in length:
This statement is always true for any parallelogram. The opposite sides must be congruent or equal in length.
3. Opposite angles are equal:
This statement is always true for any parallelogram. The opposite angles must be congruent or equal in measure.
4. Diagonals bisect each other:
This statement is always true for any parallelogram. The diagonals of a parallelogram bisect each other, meaning they intersect at their midpoints.
5. All angles are right angles:
This statement is not always true about a parallelogram. While a rectangle is a special type of parallelogram where all angles are right angles, not all parallelograms have right angles. There are other types of parallelograms, such as squares and rhombuses, that have different angles.
Therefore, the statement "all angles are right angles" is not always true about a parallelogram.
