A trapezoid (or trapezium, outside of North America) has two parallel sides.
The more common definition is a four-sided figure with exactly one pair of parallel sides. By this definition, figures with two sets of parallel sides such as a rectangle are nottrapezoids.
Some mathematicians use a more general definition that allows for one or more pair of parallel sides. By this definition, a rectangle, square, or rhombus would be considered as special cases of a trapezoid.
1 pair of parallel line
A trapezoid has 1 pair of opposite parallel lines of different lengths.
A trapezoid is a quadrilateral with one pair of sides parallel.
Exactly one pair.
A trapezoid has one pair of parallel sides.
1 pair of parallel lines
1 pair of parallel line
A trapezoid has 1 pair of opposite parallel lines of different lengths.
A trapezoid is a quadrilateral with one pair of sides parallel.
Exactly one pair.
Only one pair is parellel.
A trapezoid has one pair of parallel sides.
An isosceles trapezoid has 1 vertical line of symmetry
The non-parallel line of an isosceles trapezium are equal.
A trapezoid is a quadrilateral with two parallel sides of unequal length. It's like a triangle with the top removed and replaced by a line parallel to the bottom line.
A trapezoid has 1 pair of opposite parallel sides of different lengths
Not always take a trapezoid for example.
