Parallel. Their is no simpler term for there definition.
parallelogram
sides are congruent angles are congruent sides are paralell
a square has 4 sides
A shape with two pairs of parallel sides is ........ a parallelogram!
no, a parallelogram has two pairs of parallel sides, a trapezium has exactly one pair of paralell sides
yes because a paralellogram has two sets of paralell sides and a square does too and opposite sides are equal in length and opposite angles are congruent yes because a paralellogram has two sets of paralell sides and a square does too and opposite sides are equal in length and opposite angles are congruent
Only once at, a right angle. Paralell lines never meet.
It has 1 pair of opposite parallel sides of different lengths
Yes, the only limiting factor of a trapezoid is that it can only have one set of paralell sides.
Any shape with four sides is a quadrilateral. With four unequal sides, it would either be a trapezium or trapezoid, dependant upon whether any of the sides are paralell to each other (which would make it a trapezoid).
its called the 38th paralell
It need not have any.If it has an even number of sides, say 2n (where n>1), then it can have n pairs of parallel sides.If it has an odd number of sides, say 2n+1 (where n>1), then it can have n pairs of parallel sides.
