Question

Polygon ABCDE is the result of a reflection of polygon LMNOP over the line. Which line segment in the image corresponds to PL¯¯¯¯¯ in the pre-image?
AB¯¯¯¯¯

BC¯¯¯¯¯

DE¯¯¯¯¯

EA¯¯¯¯¯

CD¯¯¯¯¯
AND
Triangle ABC has vertices A(5, 3) , B(3, 7) , and C(1, 4) . Triangle ABC is dilated, and the vertices of the image are A′(2.5, 1.5) , B′(1.5, 3.5) , and C′(0.5, 2) . The center of dilation is the origin.

What is the scale factor of the dilation?


0.25

0.5

2

4

Answer 1

EA__

(my Underscore in the wrong place)

because of it's placement n' stuff.

Then 0.5 because the numbers are halved

Answer 2

DE⁻⁻ for the top question.

and


0.5 for the bottom question.
