parallelogram    
n. 平行四边形

平行四边形

parallelogram
n 1: a quadrilateral whose opposite sides are both parallel and
equal in length [ant: {trapezium}]

Parallelogram \Par`al*lel"o*gram\, n. [Gr. ?; ? parallel ? to
write: cf. F. parall['e]logramme. See {Parallel}, and
{-gram}.] (Geom.)
A right-lined quadrilateral figure, whose opposite sides are
parallel, and consequently equal; -- sometimes restricted in
popular usage to a rectangle, or quadrilateral figure which
is longer than it is broad, and with right angles.
[1913 Webster]

{Parallelogram of velocities}, {parallelogram of forces},
{parallelogram of accelerations}, {parallelogram of momenta},
etc. (Mech.), a parallelogram the diagonal of which
represents the resultant of two velocities, forces,
accelerations, momenta, etc., both in quantity and
direction, when the velocities, forces, accelerations,
momenta, etc., are represented in quantity and direction
by the two adjacent sides of the parallelogram.
[1913 Webster]

  • How do the areas of the parallelograms compare? - Brainly. com
    Again, if parallelogram 2 has an area x, then parallelogram 1 would be x + 2 If statement 3 is true , it means both areas are identical: Area of parallelogram 1 (x) = Area of parallelogram 2 (x)
  • Quadrilateral WXYZ is shown. Diagonals are drawn from point W to point . . .
    The statement that the diagonals of a parallelogram bisect each other is a fundamental property of parallelograms in geometry, which is widely recognized and used in various proofs and applications
  • [FREE] Given: AD ≅ BC and AD ∥ BC Prove: ABCD is a parallelogram . . .
    Reason: Parallelogram Side Theorem states that if in a quadrilateral one pair of opposite sides are both equal and parallel, then that quadrilateral is a parallelogram chevron down Examples Evidence
  • Which shape is both a parallelogram and a rhombus - Brainly. com
    A parallelogram is a quadrilateral (four-sided shape) with both pairs of opposite sides parallel A rhombus, on the other hand, is also a quadrilateral with all four sides of the same length A square, with all sides equal and all angles 90 degrees, aptly fits both these descriptions
  • KLMN is a parallelogram. - Brainly. com
    Property of Parallelograms: In a parallelogram, the opposite angles are congruent This means that angle K (K) is equal to angle M (M): ∠ K = ∠ M Explanation: This property stems from the basic definition of a parallelogram where two pairs of opposite sides are parallel When you have parallel lines and a transversal, alternate interior
  • Figure PQRS is a parallelogram. - Brainly. com
    In any parallelogram, if one angle is known, the opposite angle will be the same, while the adjacent angles will sum up to 180 degrees For instance, if you have a parallelogram where one angle is found to be 70 degrees, the opposite angle will also be 70 degrees, and the two adjacent angles will each be 110 degrees (since 70 + 110 = 180)

  • [FREE] The diagram shows a shaded parallelogram drawn inside a . . .
    The area of the shaded parallelogram is 40cm^2 In geometry, the area of a parallelogram is indeed calculated by multiplying its base by its height This principle holds true for the shaded parallelogram depicted in the diagram With the base of the parallelogram measured at 10 cm and the height at 4 cm, we can apply the formula: Area = base
  • Parallelogram WXYZ is shown. Diagonals are drawn from point W to point . . .
    For example, in parallelogram formed by points A, B, C, and D with diagonals intersecting, the properties of the diagonals can similarly be used to find segment lengths by setting equal the expressions for each segment created by their intersections
