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]

    Examples Evidence 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 The properties of parallelograms indicate that diagonals bisect each other
  • Figure CDEF is a parallelogram. - Brainly. com
    A parallelogram is a quadrilateral with two pairs of parallel sides The opposite sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure
  • Parallelogram MNPQ was dilated to create parallelogram MNPQ.
    To analyze the relationship between parallelogram MNPQ and its dilated image M'N'P'Q', we first calculate the lengths of the corresponding sides and then determine the factor of dilation

  • Parallelogram PQSR is shown. The length of - Brainly. com
    An example of this concept can be seen in a rectangle, which is a special type of parallelogram, where opposite sides are equal in length Similarly, any parallelogram, including a rhombus or a square, shares this property of congruent opposite sides
  • The diagonals of a parallelogram are congruent. Which could be the . . .
    A parallelogram has two pairs of parallel and congruent sides The parallelogram that fits the given definition is (b) rectangle From the definition of parallelograms, we can conclude that the trapezoid is not a parallelogram This is so, because the opposite sides are not congruent Kites and rhombus are parallelograms but the diagonals of a kite and a rhombus are not equal However, the
  • [FREE] The diagram shows a shaded parallelogram drawn inside a . . .
    The area of the shaded parallelogram can be calculated using the formula A = b*h, where A represents area, b represents base, and h represents height Typically, the base and height of the parallelogram share measurements with the rectangle it's inside of
  • Prove the Parallelogram Side Theorem: - Brainly. com
    The Parallelogram Side Theorem states that in a parallelogram, opposite sides are equal By analyzing triangles formed within the parallelogram, we can prove that AB ≈ CD and BC ≈ DA using congruence principles
  • the diagram shows a parallelogram. work out the value of x
    To find the value of x in a parallelogram, we use the properties of parallelograms and the relationship between their angles In any parallelogram, opposite angles are equal, and consecutive angles are supplementary, meaning they add up to 180°
  • [FREE] Find the area of the following parallelogram: 3 cm 5 cm 4. 5 cm A . . .
