# What is a parallelogram with four angles

## Parallelogram - definition and features

A parallelogram (also called "rhomboid") is a square, a geometric figure that consists of 4 sides. The 2 opposite sides are the same length and parallel to each other. Adjoining sides each form angles that can assume sizes between and. The sum of all interior angles is.

A parallelogram is a square with opposite sides of the same length and parallel to each other. Two angles are each the same size. ### Features of the parallelogram

• The parallelogram has 4 corners, 4 sides and 1 surface.
• All interior angles are between and large.
• The opposite angles are the same.
• The parallelogram is point-symmetrical to its origin.
• The surface diagonals have different lengths, provided that all angles are unequal.
• The surface diagonals intersect at a point that bisects both diagonals.
• If you look at the intersection of the two surface diagonals and all points of the parallelogram, you can see 2 mutually congruent (congruent) triangles.
• A parallelogram belongs to the group of polygons (polygons).
• If all sides of the parallelogram are at right angles to each other (or if all interior angles are right angles), one speaks of a rectangle. If all sides are also of the same length, one speaks of a square.
• If all sides of the parallelogram are of the same length and the interior angles are not right angles, one speaks of a rhombus.
• The parallelogram equation is.
• There is no inscribed circle and no circumference.
