Question 349653
A rectangle with side lengths 3h and k has a vertex at (-h,k ). which point cannot be a vertex of the rectangle  ?

A (h,k)   B  (-h,0)  C  (2h,0)  D  (2h,k)


2 of the rectangles sides are 3h in length
the other 2 sides are k in length
vertex is another word for a corner of the rectangle
rectangles have 4 vertices (vertices is the plural of vertex)
one vertex of this rectangle is (-h, k)
so the length of this rectangle is 3h, and the height (width) is k


visualizing from left to right the vertices of the rectangle:


(-h, k)  ---> (-h + 3h, 0 + k)
    |             |
    |             |
(-h, 0)   ---> (-h + 3h, 0)
or
(-h, k)  ---> (2h, k)
    |             |
    |             |
(-h, 0)   ---> (2h, 0)


answers are: A (h,k)   B  (-h,0)  C  (2h,0)  D  (2h,k)
which of these is not a vertex?


(-h, 0) is, (2h, 0) is, (2h, k) is


answer is A (h,k) , that is not a vertex
