Question

3. Which of the following is true for an isometry? (1 point)
The preimage and the image are congruent.
The preimage is larger than the image.
The preimage is smaller than the image.
The preimage is the same position as the image.

Answer 1

4. RSV has coordinates R(2, 1), S(3, 2), and V(2, 6). A translation maps points R to R' at (–4, 8). What are the coordinates for S' for this translation? (1 point)
(–6, –4)
(–3, 2)
(–3, 9)
(–4, 13)


Help please on both of these two questions!!!

Answer 2

Isometry: a transformation that preserves congruence. In other words, a transformation in which the image and preimage have the same side lengths and angle measurements. The following transformations maintain their mathematical congruence. Review transformations at this site:

Answer 3

A translation maps points R(2, 1) to R' at (–4, 8).
--------------
The translation takes point R six units to the left and seven units up to its image R'.
( (2 - 6) , (1 + 7) ) or (-4, 8).

So, to what coordinates of point S' does that same translation take S(3, 2) ?
