Question

Triangle KLM was dilated according to the rule

Answer 1

Answer:

Correct choices are A, B and D

Step-by-step explanation:

The rule DO,0.75 (x,y) is a dilation by a scale factor of 0.75 about the origin. This rule can be rewritten as

(x,y)→(0.75x,0.75y) (option A is true).

The dilation preserves parallel lines, then LM is parallel to L'M' (option B is true).

According to the rule of dilation, $K'M'=0.75KM,$ this means that K'M' is shorter than KM (option C is false).

The vertices of the image are placed on the segments that connect origin with vertices of the pre-image triangle, then the vertices of the image are closer to the origin than those of the pre-image (option D is true).

The distance from M' to the origin is exactly 0.75 times the distance from M to the origin (option E is false).

Answer 2

The answer is
A. DO, 0.75 (x,y) = (0.75x, 0.75y)
B. LM is parallel to L'M'.
and C. The vertices of the image are closer to the origin than those of the pre-image.
