Is WXYZ a parallelogram?

c) WXYZ cannot be a parallelogram because there are three different values for x when each expression is set equal to 15. d) WXYZ cannot be a parallelogram because the value of x that makes one pair of sides congruent does not make the other pair of sides congruent.

What properties of parallelograms can be used to prove parallelogram theorems select all that apply?

There are six important properties of parallelograms to know:
  • Opposite sides are congruent (AB = DC).
  • Opposite angels are congruent (D = B).
  • Consecutive angles are supplementary (A + D = 180°).
  • If one angle is right, then all angles are right.
  • The diagonals of a parallelogram bisect each other.

Where ABCD is a parallelogram?

9.3.

II. A parallelogram : In a quadrilateral, if both pairs of opposite sides are parallel and equal, then it is called a parallelogram. i.e., AB || CD and AB = CD; AD || BC and AD = BC, then ABCD is a parallelogram.

How do you prove a parallelogram is a vector?

Answer: Let A, B, C, D be the four sides; then if the vectors are oriented as shown in the figure below we have A + B = C + D. Thus two opposite sides are equal and parallel, which shows the figure is a parallelogram.

What is the perimeter of parallelogram WXYZ?

What type of quadrilateral is ABCD?

A quadrilateral is called a parallelogram, if both pairs of its opposite sides are parallel. AB ∥ DC and AD ∥ BC. So, ABCD is a parallelogram. A parallelogram having all sides equal, is called a rhombus.

Which of the following is wrong about parallelogram?

Opposite angles are bisected by the diagonals. The above statement is not true for every parallelogram. It is true only for a rhombus (diamond) or square where the diagonals bisect the opposite angles they connect, and diagonals are perpendicular.
