A dilation produces a similar figure
True
False
When the scale factor of a dilation is less than one, the dilation is a reduction (gets smaller).
True
False
A dilation produces a congruent figure
True
False
State the coordinate of the image of the given point B (2,-9) under a dilation with center at the origin with the given scale factor k = 2.
(2, 9)
(4, -7)
(4, -18)
(1, -4.5)
A polygon is transformed by a rule (ax, ay). Which of the following is true?
If a > 1, the image of the polygon is congruent to the polygon.
If a < 1, the image of the polygon is congruent to the polygon.
If a > 1, the image of the polygon is smaller than the polygon.
If a > 1, the image of the polygon is larger than the polygon.
A polygon will be dilated on the coordinate grid to create a smaller polygon. The polygon is dilated using the origin as the center of dilation. Which rule could represent this polygon?
(.5 + x, .5 + y)
( x - 1, y - 1)
(1.5x, 1.5y)
(0.7x, 0.7y)
Would a dilation with a scale factor of 0.75 be a reduction or an enlargement?
Reduction
Enlargement
