Question

EMERGENCY: PLEASE ANSWER AS SOON AS POSSIBLE

Joseph is creating a dilation through point B with a scale factor of 2. Which statements about the dilation are correct? Check all that apply.

Triangle A B C. Angle B is a right angle.

A’ will be located on ray Ray B A.

B and B’ are the same point.

Line segment B prime C prime will be One-half as long as Line segment B C.

Line segment A B and Line segment B C will be part of the image’s sides.

The image will be inside the pre-image.

Answer 1

Triangle A B C. Angle B is a right angle.

Explanation:

A dilation with a scale factor of 2 represents a transformation where the preimage ABC would be smaller and the triangle A'B'C' would be twice bigger. That means, the pre-image will be inside the image.

Also, as you can observe in the image, angle B is a right angle. Triangle A'B'C' has B' as a right angle too.

Additionally, line segment B'C' is twice bigger than line segment BC, because the preimage is smaller.

Therefore, the only right answer is the first one.
