It is any one of the four vertices (corners) of the trapezium.
It fits the description of a trapezoid
a right trapezoid
it doesn't normally but it can and still be a trapezoid
A trapezoid can have either one or two acute angles.
Yes
no
you can't a trapezoid can never really have a right angle if it does it is no real trapezoid. -------------------------------------------------------------------------------------------------------------- all the way -------------------------------------------------------------------------------------------------------------- ___ Actually you can. Instead of having to angled sides: / \ ___ You make it be: | \ It's still a trapezoid but an irregular one. --------------------------------------------------------------------------------------------------------------
NO. A trapezoid cannot be a rectangle. If a parallelogram has one right angle then it is a rectangle. A trapezoid doesn't satisfy this condition because a trapezoid is a quadrilateral with exactly one parallel side which means that it doesn't have a right angle.
A regular trapezoid (!) is a square. And each interior angle of a square is 90 degrees.
In general, trapezoids do not have right angles. In fact, a trapezoid with a right angle is a special case, called a rectangle.
No. A trapezoid need not have any right angles.
yes
