Because if they were parallel but not equal, the other two sides would not be parallel.
In parallelogram each two opposite sides are parallel and equal in length
Congruent (equal in length), and parallel.
Yes. A parallelogram is defined as having opposite sides that are parallel and equal in length, and opposite angles that are equal.
A parallelogram.
A parallelogram is defined as a four-sided shape, with opposite sides of equal length and opposite angles equal.
Yes. A parallelogram has two pairs of opposite sides parallel (and each pair of equal length). A rhombus has two pairs of opposite sides parallel (and each of those pairs of opposite sides are of equal length), thus it is a parallelogram. It is a special case of parallelogram where all four sides are equal in length, not just the opposite pairs.
In parallelogram each two opposite sides are parallel and equal in length
Yes A parallelogram has opposite sides parallel and equal in length. Does a rectangle have opposite sides parallel and equal in length? Yes Thus a rectangle is a parallelogram.
Both shapes have 4 sides, two pairs equal in length. In a parallelogram the equal length sides are opposite each other. In a kite the equal length sides are adjacent.
No. By the very definition of a parallelogram, it's opposite sides of are equal length.
Yes. By definition, opposite sides are equal (i.e. same length) and parallel.
equal in length.
equal in length.
Congruent (equal in length), and parallel.
A parallelogram is a geometric quadrilateral with two pairs of parallel sides. The opposite sides and opposite angles are equal in length.
A parallelogram is a four sided shape where each of the two opposite sides are parallel. A consequence of this is that opposite sides are equal in length, and opposite angles are also equal.
Yes. A parallelogram is defined as having opposite sides that are parallel and equal in length, and opposite angles that are equal.
