Question

Could someone help me with a few questions?

Answer 1

They're geometry, and it's over dilation.

Answer 2

I know a little geometry, so I'll see if I can. If not, I'll tag some users to help.
(also just one question per post please) :)

Answer 3

Alright. First one.

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) A'B¯¯¯¯¯¯ is 1.5 units long and lies on the same line as AB¯¯¯¯¯.

B) A'B¯¯¯¯¯¯ is 3 units long and lies on the same line as AB¯¯¯¯¯.

C) A'B¯¯¯¯¯¯ is 1.5 units long but lies on a different line than AB¯¯¯¯¯.

D) A'B¯¯¯¯¯¯ is 3 units long but lies on a different line than AB¯¯¯¯¯.

Answer 4

So I'm not too sure, but I think it will be A or C.
