We don't know who said that, but it's not true. 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 quadrilaterals
that aren't trapezoids.

Is a quadrilateral a trapezoid?
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.
Is all trapezoids are quadrilaterals?
No but a trapezoid does belongs to the class of 4 sided quadrilaterals.
Are all trapezoids parallelograms true or false?
False but they are both 4 sided quadrilaterals
Can some trapezoids can not be a quadrangles?
No because all trapezoids are 4 sided quadrilaterals with 4 interior angles that add up to 360 degrees.
Names of quadrilaterals?
There are many different quadrilaterals such as squares, trapezoids, rectangles, rhombus and parallelogram.
Are some quadrilaterals trapezoids?
All quadrilaterals are 4 sided shapes which includes trapezoids.
Are some quadrilaterals are trapezoids?
Yes because all 4 sided shapes are quadrilaterals which includes trapezoids.

Are some trapeszoids squares?
trapezoids are trapezoids and squares are squares but all are quadrilaterals.
Are all quardrilaterals trapezoids?
All polygons with 4 sides are called quadrilaterals which includes trapezoids
Are all trapezoids parrallelograms?
No but they are all 4 sided quadrilaterals
What are the irregular quadrilaterals?
Rhombuses, rectangles, kites, parallelograms, and trapezoids are all irregular quadrilaterals.
Can All quadrilaterals can be classified as either parallelograms or trapezoids?
No because all quadrilaterals are 4 sided shapes which includes parallelograms, trapezoids, squares, rectangles, kites......etc
Are all parallelogram trapezoids?
No but they are both 4 sided quadrilaterals.
All paralelograms are trapezoids?
No but they are both 4 sided quadrilaterals
What are the six types of quadrilaterals?
There are many types of quadrilaterals. These include parallelograms, rectangles, squares, rhombuses, trapezoids, scalene trapezoids, right-angled trapezoids, and isosceles trapezoids.
