... Dilation = A transformation that is not rigid. Preserves the shape of an object, but the size may vary. (Example: Your eyes will dilate to adjust to brightness). Dilations can be found on a coordinate plane by multiplying the x and y coordinates of a point by the same number n. D(x, y) = (nx, ny) Th ...

5-6 Inequalities in One Triangle
... Proof: Assume temporarily that y = 6. Then 7(x + 6) = 70; divide each side by 7 to get x + 6 = 10 and so x = 4. But this contradicts the given statement that x ≠ 4. The temporary assumption that y = 6 led to a contradiction, so we can conclude that y ≠ 6. ...
