spiral review
11 which transformations are considered rigid motion?
12 h(12, 8) is translated using the following vector <1, -5>. give the coordinates of h.

Explanation:

Step1: Recall rigid - motion transformations

Rigid - motion transformations preserve shape and size. Translations, rotations, and reflections are rigid - motion transformations.

Step2: Calculate the new coordinates for translation

For a point $(x,y)$ translated by a vector $\langle a,b
angle$, the new coordinates $(x',y')$ are given by $x'=x + a$ and $y'=y + b$. For point $H(12,8)$ and vector $\langle1,-5
angle$, we have $x'=12 + 1=13$ and $y'=8+( - 5)=3$.

Answer:

1. Translations, rotations, and reflections are considered rigid - motion.
2. The coordinates of $H'$ are $(13,3)$.
