Question

The coordinates of Trapezoid EFGH are E(4, 8), F(1, 2), G(6, 1), and H(8, 8). The image of EFGH under dilation is E'F'G'H'.
If the coordinates of vertex H' are (4, 4), what are the coordinates of vertex E'?

Answer 1

Select one:
a. (1, 2)
b. (2, 4)
c. (2, 2)
d. (0, 4)

Answer 2

Answer 3

what do you think?

Answer 4

I think its B but not sure

Answer 5

The dilation ratio is 1:2 as evidenced by H (8,8) --> H' (4,4).

So, for E (4, 8), then E' coordinates would be one-half those of E.

@prowrestler That would be what you thought. >>> I think its B but not sure

Answer 6

you cant thunk you have to know

Answer 7

ok one more

Answer 8

Kyra is using rectangular tiles of two types for a floor design. A tile of each type is shown below.

Answer 9

I'm quoting you. You posted this statement, >>> I think its B but not sure -- NOT me.

Answer 10

Which statement is correct?

Answer 11

These are the lengths to consider with looking at the options.

Answer 12

Recall that lengths of corresponding sides of similar polygons have to be in proportion.

Answer 13

So PQ/JK = 7/4 and QR/KL = 4/3.
7/4 is not equal to 4/3 and corresponding sides are not in proportion.
The tiles are not similar.

The proportions can be written as PQ/QR = JK/KL which means yet again that the tiles are not similar as correctly stated in OPTION FOUR. @prowrestler
