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]

  • 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)
