the lines are parallel, parallel lines have same slope, thus the slope of A'B'=sloe AB=-2

In ΔABC, ∠ ABC is a right angle included between AB¯¯¯¯¯ = 3 units and BC¯¯¯¯¯ = 2 units. ΔABC is dilated by a scale factor of 0.5 with point B as the center of dilation, resulting in the image ΔA′B′C′. Which statement about A'B¯¯¯¯¯¯ is true?

anonymous · Answer

A'B¯¯¯¯¯¯ is 1.5 units long and lies on the same line as AB¯¯¯¯¯.

A'B¯¯¯¯¯¯ is 3 units long and lies on the same line as AB¯¯¯¯¯.

A'B¯¯¯¯¯¯ is 1.5 units long but lies on a different line than AB¯¯¯¯¯.

A'B¯¯¯¯¯¯ is 3 units long but lies on a different line than AB¯¯¯¯¯.
