Question

2. Consider polygon ABCD with coordinates A(8,12), B(10,4),C(4,4),D(2,8).

Answer 1

Answer:

Step-by-step explanation:

Lets take point A:

Reflection across the line y = 2 moves the point to

(8, -8)

A dilation of 1/2 will bring the above point to (1/2*8, 1/28-8= (4, -4).

So for the other points we have

B(10,4)-->B'(10, 0)---> B"( 5, 0)

C(4, 4)--> C'(4, 0) ------C"(2, 0)

D(2, 8)----D'(2, -4)---->D"(1, -2)

Answer 2

Find the coordinates after reflection: A′(8,−8)andB′(10,0)andC′(4,0)andD′(2,−4)

Find the coordinates after reflection: A′(8,−8)andB′(10,0)andC′(4,0)andD′(2,−4)Find the coordinates after dilation: A″(4,−4)andB″(5,0)andC″(2,0)andD″(1,−2)
