What are dilations, similarity and scale factors

👉 Learn about dilations. Dilation is the transformation of a shape by a scale factor to produce an image that is similar to the original shape but is different in size from the original shape. A dilation that creates a larger image is called an enlargement or a stretch while a dilation that creates a smaller image is called a reduction or a shrink. The measures of the sides of the original shape and the corresponding sides of the image are proportional. And the distance of the parts of the original shape from the origin are proportional to the distance of the corresponding parts of the image.

I'm in 9th grade and the STAAR test is coming up and I'm going to fail if I don't start understanding almost everything it's going to be going over

[deborahallyjoseph]

Loved the illustration of the enlargements, original and reductions all on the same 3 lines which converge at the point of dilation

[fayecervantes]

do you so chunking or rally coaching..what do you do to get class involved?

[nigerunda]

what if the dilation centre isn't on the coordinate centre(0;0)

[babylon]

Thanks man that really helped me keep it up I subbed 👍🏾

[joshlee]

*Dilations, not "Dialations"
But great vid anyway, helpful

[wanita]

What happens if they give the scale factor as a fraction

[ishaana.]

really helped me, but you spelled dilations wrong lol, but it was really helpful
