Question

Which property is not a characteristic of a parallelogram?

O A. Opposite sides are congruent.
B. All angles are congruent.
O C. Opposite sides are parallel.
D. Opposite angles are congruent.

Answer 1

The property that is not a characteristic of a parallelogram is that all angles are congruent.

Step-by-step explanation:

A parallelogram is a four-sided polygon with opposite sides that are parallel and equal in length. Opposite angles are also equal. The sum of interior angles is 360 degrees. Common properties include opposite sides being equal and opposite angles being equal. The correct answer is B. All angles are congruent.

A parallelogram is a quadrilateral with two pairs of parallel sides. Its properties include:

1. Opposite sides are congruent (same length).
2. Opposite sides are parallel (never intersect).
3. Opposite angles are congruent (same measure).

However, all angles in a parallelogram are not necessarily congruent. The measures of the adjacent angles can differ, resulting in unequal angles.
