Which representation of a transformation on a coordinate grid preserves congruence?

Mathematics
1 answer:
Zepler [3.9K]3 years ago

Answer:

Rotations, reflections and translations.

Step-by-step explanation:

Rotations, reflections and translations are transformations that preserve the both the angle measurements and the lengths of the sides, so congruence is preserved.

Dilations are transformations that keep the angle measurements, but the side lengths change, so the transformation is similar, not congruent.

Complete Question

The complete question is shown on the first uploaded image

Answer:

The score of the student is  x = 779.42

Step-by-step explanation:

Generally we can mathematically represent the z-score as

         z =  \frac{x - Mean}{ stDev}

Here x is the score of the student

substituting 1045.7 for the Mean, 221.9 for the stDev and -1.2 for z we have  

          -1.2 =  \frac{x - 1045.7 }{ 221.9}

=>       -266.28 =  x -1045.7

=>     x  =  -266.28 + 1045.7

=>     x = 779.42
