Diagonally opposite pairs of angles will always be equal, but the only time all angles in a quadrilateral parallelogram are equal is when that shape is a rectangle.
That depends on what type of a 4 sided quadrilateral it is but in generals the 4 interior angles of any quadrilateral always add up to 360 degrees.
No. For any random quadrilateral, they are actually "never" congruent. The probability of the sides being so is infinitely less than the probability they will not be.
There are instances that quadrilateral angles can be consecutive and opposite angles are congruent. The best examples are square and rectangle.
No, they are supplementary.
False :]
always
a circumscribed triangle is a circumscribed triangle and will always be
A square, always, a rhombus, always, a parallelogram, always, and rectangles, always.
opposite angles are supplementary
It is a rectangle.

Yes. A quadrilateral is any plane figure bounded by four straight lines. A parallelogram has both pairs of opposite sides parallel and is therefore a special kind of quadrilateral.
