How to determine the scale factor of a dilation for enlargement

👉 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.

Love this man got me thbrough 7th skipping 2 years to algebra... best teacher ever

I usually have to explain it by saying preimage and image, so A would be the preimage, or original triangle, while B is the image, the triangle that had experienced change.

What if they gave us a point but we need to find the scale factor ?

[izetico]

Bro I have a quiz tomorrow and I didn't know how to find it you saved me thank you

[AlexanderArgyros]

Thank you so much your a live saver
Hope your living ur best life

[nishakaygayle]

Thanks sooo much for this video really appreciate it God bless

[Nan-mfvu]

What if we use different order of number on d line

[vibhurola]

But what if the coordinates are /1, 5 2, 3

[sherimasherian]

If it wasn't for him I would be failing math XD thanks man!!

[yeyetsisonline]

My question is what if B is smaller than A? Do I do the same?
