## Parallelogram Properties

1. Opposite sides of a parallelogram are pairwise equal
2. Opposite angles of a parallelogram are equal in pairs
3. The sum of adjacent (adjacent) angles of a parallelogram is 180 degrees
4. Sum of all angles is 360 °
5. The parallelogram diagonals intersect and the intersection is halved
6. The intersection of the diagonals is the center of symmetry of the parallelogram
7. The bisector cuts off an isosceles triangle from the parallelogram

## Parallelogram features

1. If the diagonals of a quadrilateral intersect and are halved at the point of intersection, then this quadrilateral is a parallelogram.
2. If two sides of a quadrilateral are parallel and equal, then this quadrilateral is a parallelogram.
3. If opposite sides of a quadrilateral are pairwise equal, then this quadrilateral is a parallelogram.
