When their equations represent same slopes and different y intercepts. The sides don't ever dissect (meaning they don't cross paths or meet).
2There are two parallel sides....A rhombus has two pairs of opposite parallel sides.There are two parallel sides....A rhombus has two pairs of opposite parallel sides.
A trapezium has two parallel sides (of unequal length) and two non-parallel sides.
a trapezoid
trapezoid
Two sides of a quadrilateral can be parallel.
Squares, rectangles, parallelograms and rhombuses have two parallel sides. The other two are also parallel. A trapezium has only two parallel sides.
A trapezoid has two parallel sides and two non parallel sides.
A parallelogram has two pairs of parallel sides.
Yes (the sides are parallel in pairs - two of the sides are parallel, and the other two are parallel among themselves).
A quadrilateral with only two parallel sides is only a quadrilateral ...... because we don't know whether the parallel sides ar equal or not .............. so it is only a quadrilateral ............
Yes, a square has two pairs of parallel sides.
With great difficulty. Or to put it another way, you also need to know the distance between the two parallel sides and the offset of the two parallel sides.
