No trapezoids are not parallelograms. Trapezoids are actually quadrilaterals and they have one pair of opposite sides. Parallelograms by definition have 2 pairs of parallel sides.

A quadrilateral is a two-dimensional shape with four sides. Some examples of shapes that are quadrilaterals are: square, rectangle, parallelogram, rhombus.

false

i hope that this answers all parallelogram questions: a parallelogram is a quadrilateral with angles that add up to 360 degrees. It has 2 parallel pairs of sides, so 4 sides. There may or ma not be lines of symmetry in a parallelogram. Some examples are squares, rhombuses, rectangles, etc.

Not EVERY quadrilatiral. Some, for instances :Rectangles, Squares, Parallelograms and Rhombus' are, as they have 2 sets of parellel lines that are equal. (As in the opposite lines are equal with each other) however you could draw a four sided shape with irregular sides. * * * * * No. The only regular quadrilateral is a square. Being a regular polygon requires all sides as well as all angles to be equal. A rectangle fails the first requirement, a parallelogram and a rhombus fail the second - unless they are squares.

All quadrilaterals are 4 sided shapes which includes trapezoids.

Yes because all 4 sided shapes are quadrilaterals which includes trapezoids.

No. Those two figures are distinct. Neither is a special case of the other.

No, a quadrilateral isn't always a trapezoid. One way to consider it is that all trapezoids are quadrilaterals (four-sided shapes), but not all quadrilaterals are trapezoids. Some quadrilaterals are concave quadrilaterals, some are scalene convex quadrilaterals (called trapezoids in the UK), some would be trapezoids, and some would be parallelograms (rectangles, squares, rhomboids, rhombi). If parallelograms are considered a special case of trapezoids, then trapezoids would include all non-scalene convex quadrilaterals, which is a highly inclusive definition.

trapezoids are trapezoids and squares are squares but all are quadrilaterals.

No. Some quadrilaterals are trapezoids and some aren't.A quadrilateral is any drawing with four sides.A trapezoid is any drawing with four sides and two of the sides are parallel.So all trapezoids are quadrilaterals. But there are a lot of other quadrilateralsthat aren't trapezoids.

Some are, and some are not. A trapezoid is a special kind of quadrilateral ... one in which two of the four sides are parallel. So all trapezoids are quadrilaterals, but there are also a lot of other quadrilaterals that are not trapezoids.

No because a trapezoid only has 1 pair of parallel sides whereas a parallelogram has 2 pairs of parallel sides but they are both 4 sided quadrilaterals.

We don't know who said that, but it's not true. Some quadrilaterals are trapezoidsand some aren't.A quadrilateral is any drawing with four sides.A trapezoid is any drawing with four sides and two of the sides are parallel.So all trapezoids are quadrilaterals. But there are a lot of other quadrilateralsthat aren't trapezoids.
