Answer:
<h2>Triangle A B C. Angle B is a right angle.</h2>
Step-by-step 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.
