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. Visa mer In Euclidean geometry, a parallelogram is a simple (non-self-intersecting) quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a … Visa mer • Opposite sides of a parallelogram are parallel (by definition) and so will never intersect. • The area of a parallelogram is twice the area of a … Visa mer To prove that the diagonals of a parallelogram bisect each other, we will use congruent triangles: $${\displaystyle \angle ABE\cong \angle CDE}$$ (alternate interior angles are equal in measure) (since these are … Visa mer • Rectangle – A parallelogram with four angles of equal size (right angles). • Rhombus – A parallelogram with four sides of equal length. Any parallelogram that is neither a … Visa mer A simple (non-self-intersecting) quadrilateral is a parallelogram if and only if any one of the following statements is true: • Two … Visa mer All of the area formulas for general convex quadrilaterals apply to parallelograms. Further formulas are specific to parallelograms: A parallelogram with … Visa mer Automedian triangle An automedian triangle is one whose medians are in the same proportions as its sides (though in a … Visa mer darling in the franxx genista
