Which statement about quadrilateral WXYZ can be proved to be true?

a. Diagonals of WXYZ are congruent.

b. Consecutive angles of WXYZ are supplementary.

c. The diagonals of WXYZ bisect opposite angles.

d. Consecutive angles of a parallelogram are congruent.

A. Diagonals of WXYZ are congruent

Step-by-step explanation:

If the quadrilateral is a rectangle, the diagonals of a rectangle are congruent

Similarly an isosceles trapezoid is a quadrilateral that must have congruent diagonals. A square, because it is a rectangle, is a quadrilateral that must congruent diagonals. But it is possible to have a quadrilateral with no additional properties that may have congruent diagonals.

The Answer is C

Step-by-step explanation:

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option

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.
