LOL, draw an equilateral triangle with centroid at origin or a circle with center at origin and radius = 1.
for the circle
a it just gets to be a bigger circle (so it is similar)
b same deal, smaller circle but similar.
c try it, I think it will be kind of elliptical (do you know how to prove that?)
d like a but it moves up.
e right and down?
f do you mean 1/(2x) as you wrote it or (1/2)x ? If 1/(2x) then try some points on the circle and see what you get.
Changing Shapes
1.)Suppose you are going to be designing a logo for a club at your school. To prepare for this product, draw a non-rectangular shape in the coordinate plane so that portions of the shape are in each of the four quadrants. Explain what would happen to your shape if you transformed it using each of the given rules with the center of dilation at the origin.
a. (4x, 4y) b. (0.25x, 0.25y) c. (2x, y)
d. (3x, 3y+5) e. (x+5, y-5) f. (1/2x, 1/2y)
2.) Will any of the transformed figures be similar to the original? Explain.
I have no idea in either two of the questions so help would be appreciated.
