Hi, I need help with this transformation lesson. I'll post 5 at a time.

1. An angle changes in size as it undergoes a dilation.

A False

B True

2. A line segment usually decreases in size under contraction.

A False

B True

3. There can only be one obtuse angle in a triangle.

A False

B True

4. If a figure is reflected across the x-axis it is congruent to the original figure.

A False

B True

5. A figure derived from a previous figure by rotation, translation or dilation will be congruent to the original figure.

A False

B True

I think there are things in my story that have helped my creativity. Your father being killed, for instance, is one of the best things that could happen to a kid if he's going to write poetry or songs.
