Problema Solution
ΔABC is dilated by a scale factor of 0.5 with the origin as the center of dilation, resulting in the image ΔA′B′C′. If A = (2, 2), B = (4, 3), and C = (6, 3), what is the length of B'C'¯¯¯¯¯¯¯ ?
Answer provided by our tutors
B'C' = 0.5*BC
BC^2 = (6 - 4)^2 + (3 - 3)^2
BC = 2
B'C' = 0.5*2
B'C' = 1
The length of B'C' is 1.
