WebA parallelogram is a quadrilateral made from two pairs of intersecting parallel lines. There are several rules involving: the angles of a parallelogram the sides of a parallelogram the diagonals of a parallelogram Rule 1: Opposite sides are parallel Read more Rule 2: Opposite Sides are Congruent Read more Web11 okt. 2024 · If two of the angles of a parallelogram are acute, then the other two angles will be obtuse. Since a parallelogram contains two pairs of parallel sides, both of the acute angles and both of the obtuse angles respectively will measure the same. I have four congruent sides two obtuse angles two acute angles and two pairs of parallel sides. …
A parallelogram has rotational symmetry of order 2 (through 180°) (or order 4 if a square). If it also has exactly two lines of reflectional symmetry then it must be a rhombus or an oblong (a non-square rectangle). If it has four lines of reflectional symmetry, it is a square.
