The statement that  correct for Triangle ABC. and Triangle A prime B prime C prime is:

  • Option b: Triangle A prime B prime C prime. is obtained by dilating Triangle ABC by a scale factor of 1 over 3 and then rotating it about the origin by 180 degrees.

What happens when a triangle is dilated?

If a triangle is dilated by scale factor, the base and height are known to be altered by the scale factor and also the area is also altered by  the said factor.

Note that if there is a scale distances between points, dilations do not alter angles.

Since:

A'(-1, -1) = (-1/2) × A(2, 2)

B'(-1, -5) = (-1/2) × B(2, 10)

C'(-4, -6) = (-1/2) × C(8, 12)

Rotation by 180° negates is seen in both of the coordinates. It is said to be the equivalent to reflection across the x-axis and also the  reflection across the y-axis.

Therefore, The statement that  correct for Triangle ABC. and Triangle A prime B prime C prime is:

  • Option b: Triangle A prime B prime C prime. is obtained by dilating Triangle ABC by a scale factor of 1 over 3 and then rotating it about the origin by 180 degrees.
