Can you show that this quadrilateral is a parallelogram?

➪ No, This quadrilateral cannot be proven a parallelogram because in a parallelogram a pair of opposite sides are parallel and equal. In this quadrilateral none of the sides are parallel or equal according to my observation. Thus, This cannot be proven as a parallelogram...~

Step-by-step explanation:

This can be a parallelogram if both pairs of opposite angles are equal.

We can see one pair of  angles marked as equal but there is no evidence of the other pair being equal.

So we can't state it is a parallelogram.

b. 2 and 4

step-by-step explanation:

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
