I personally consider a trapezoid to have only one pair of parallel sides. It just seems redundant to have the term parallelogram meaning two pairs of parallel sides and then have trapezoid meaning one pair of parallel sides OR two pairs (aka... a parallelogram).

[@vedhamara6748]

Ok buddy

[@WBENJONES]

My son learned a lot from this! Thanks.

[@SlipperyTeeth]

did you notice the dashes on the rectangle that told us the sides weren't congruent

[@MahaRani-fn8vb]

Trapezoid not sir trapezium

Thanks man this really helped me with my schoolwork for the lockdown.Keep it up!

[@animeprofessional4736]

Not a lockdown.

[@ryan2009cov]

In the UK, we define a trapezoid as a quadrilateral with no sides parallel.

[@devanshsharma3966]

In India, We call it a Trapezium. A quadrilateral which has one pair of parallel sides.

[@laurotorres123]

Cool

[@invisiblevisible2589]

Question, why is a square not a quad? It's a closed shape, 4 right angles like a rectangle, and all the lines are congruent.

[@sidrojinedar1307]

it is a quad.

[@MrCrafterPlaysMC]

A parallelogram does not have four 90 degree angles like a rectangle or a square, so why are we defining it as such? Why is it a parallelogram when parallelograms have angles different than that of a rectangles?

[@janinemorada7387]

Hugh Jackman I agree

[@mlijah]

It is quite the same as saying a rectangle isn't necessarily equal to a square, but a square is always equal to a rectangle. A parallelogram can be a rectangle, and all rectangles are parallelograms (because in rectangles the lines are always parallel to the opposite), which is what Sal was getting at.
