Quadrilateral WXYZ has vertices W(2, 10), X(10, 10), (10,2), and Z(2, 2). Determine if quadrilateral WXYZ is a rhombus.
Oliga [24]

Answer:

B. Yes, quadrilateral WXYZ is rhombus because the sides are perpendicular.

Step-by-step explanation:

1) according to the given coordinates the equations of the sides are:

YZ: y=2; WZ: x=2; WX: y=10; XY: x=10. It means

2) YZ⊥WZ; YZ⊥XY; WX⊥XY; WX⊥WZ. To the additional, WX=WZ=YZ=XY, then

3) the given quadrilateral is sqare (rhombus with angles m∠=90°).

4) finally, the correct answer is

B. Yes, quadrilateral WXYZ is rhombus because the sides are perpendicular.

Laura draws a right triangle she then creates three squares using each side of the triangle shown
Mamont248 [21]
The correct way of proving Pythagoras Theorem here is:
<span>4- to prove that the area of two smaller squares combined is equal to the large square

This is because Pythagoras theorem states that the sum of the square of the two smaller sides is equivalent to the square of the third side. The squares of the sides are represented as the area of the squares because the area of a square is obtained by multiplying a length by itself, or squaring it.

Why is a/0 not defined?
dolphi86 [110]
For division operations that are defined, multiplication is the inverse operation. That is if
  a/b = c
then
  a = b*c

Division by 0 is undefined because it has no inverse operation. If
  a/0 = c
it is not true that
  a = 0*c
