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?
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¯¯¯¯¯.

Best ResponseYou've already chosen the best response.0Ok. Since the center of dilation is B, the point won't change location, and since it's a point that's part of the triangle, the dilated figure will stay inside the triangle.

Best ResponseYou've already chosen the best response.0Perfect. You can now eliminate answers C and D. The next part is length. Since point A' will lie on AB and move towards B (The scale factor is less than 1), it will make A'B' smaller than AB. If you apply the scale factor to the length of AB, what is the answer?

Best ResponseYou've already chosen the best response.0Thanks so much, I've been doing this online geometry for a while now and it's been hard to understand on my own. I've had help from people who can't figure it out either, so I'm really glad i found a platform that helps me. @javierpratdesaba

Best ResponseYou've already chosen the best response.0I can totally understand you, I am in module five of the same course as you :) It can get pretty tough at times, and remember we're here for you guys :) BTY who is your geometry instructor?

Best ResponseYou've already chosen the best response.0I'm using the system called Plato, through my school. I don't have an instructor or teacher or anything of that nature. I'm on home hospital from my school doing online classes, so I essentially teach myself the best I can. @javierpratdesaba
