NAME ___Jerome Macairan___________ and PERIOD NUMBER __3__.

What is a transformation? A transformation are like rotations, reflections, and dilations.

Why is a dilated triangle not congruent to its preimage? A dilated triangle isn’t congruent to it’s preimage because of how it isn’t the same size, its bigger, it was dilated.

What would coordinates be for the triangle ABC after a dilation with scale factor 3?

A (-3, 7) B (-3, 0) C (3, 7) = A’ (-9, 21) B’ (-9, 0) C’ (9, 21)

Choose one example from the Gallery and give it a name, like “Pizza Box”.

1.) what is a transformation

A transformation is when you can move a angle up,down,left,or right.

2.) Why is a dilated triangle not congruent to the preimage

Because it does not have the same sides.

3.)what would the coordinates be if they were dilated

congruent

4.)choose one example from the gallery and name it.

zoom in zoom out the flowers

5.)say why you choose that example.

I thought the way they showed the small flowers and large flowers like simular.

Noel Kamanuwai pd. 5

1. What is a transformation?

A transformation is to “slide”, “turn”, reflect, or to dilate an image.

2. Why is a dilated triangle not congruent to its preimage?

Congruent means to have a same shape and size to the preimage. Dilation makes the image larger or smaller by x scale factor. So a dilated triangle isn’t congruent to its preimage.

3. What would coordinates be for the triangle ABC after a dilation with scale factor 3?

A (-3, 7) B (-3, 0) C (3, 7)

6. List the math vocabulary words the student used. Like “preimage, reflect, image”.

Dilation, Congruent, Similar.

7. Look up on the internet and write the official definition for all of the math words they used.

Dilation: A dilation is a transformation (notation ) that produces an image that is the same shape as the original, but is a different size. A dilation stretches or shrinks the original figure.

Congruent: 1. In agreement or harmony. 2. In identical form, coinciding exactly when superimposed.

Similar: 1. Resembling without being identical. 2. A person or thing similar to another. 3. A substance that produces effects resembling the symptoms of particular diseases.

Dilation would change how the size of the triangle, which means dilation doesn’t

work as a transformation. Congruence has to have the same shape, and same size.
