While you were explaining all the things about dilations, I was amazed at the wonderful shapes that came of them. Apparently math does have some use. :)
Ok so when u were dilating the second shape, the one that decreases,why in the first point you only multiplied the x value by the scale factor and not the y?
Don't you think the term "Center of Dilation" is confusing and misleading language????? I read your explanation wherein "'the single point where all lines meet will be the center of dilation".....Please explain why the "Math Community" does not consider the ORTHOcenter of the triangle (original figure) the center of dilation, because the orthocenter is the actual center of a triangle image....
A 1/2 dilation means the object will decrease. But, as green lin said there is no such thing as a negative dilation. As it says in the video tho a scale factor more that 1 means the object increases in size and a scale factor less than 1 means the object will decrease in size.
hush.......isn't this 8th grade math according to American standards?, thx anyway, helped me a lot to confirm my general concept of dilation on a coordinate plane
