The triangle ABC, shown on the coordinate plane above, is dilated from the origin by scale factor r = 1/2. What is the location
1 answer:
Answer:
see explanation
Step-by-step explanation:
Since the dilatation is centred at the origin with a scale factor of .
Then the coordinates of the image are one half the coordinates of the original, that is
A(3, 4 ) → A'(1.5, 2 )
B(- 7, 2 ) → B'(- 3.5, 1 )
C(2, 2 ) → C'(1, 1 )
