Here is a grid showing triangle ABC and two other triangles. You can use a rigid transformation to take triangle ABC to one of the other triangles. Which one? How?
Triangle EBD - ABC is reflected on a line at point "B"
Triangle CFG - Translate triangle ABC 7 units right so that "B" matches up with "F". Then rotate 90 degrees clockwise around "F".
Triangle CFG - Rotate triangle ABC 90 degrees counterclockwise around point "C", then rotate 180 degrees around the midpoint of segment CG.
Triangle EBD - Translate triangle ABC up two units.
Here are two line segments. Is it possible to rotate one line segment to the other? If so, find the center of such a rotation.
Yes, it is possible to rotate one of these line segments to the other. This can be done by rotating 180° around a point midway between the two lines.
No, is not possible to rotate because the only way to get one line to the other is by a translation up 5 units and then right two units.
Lin says that she can map Polygon A to Polygon B using only reflections. Do you agree with Lin? If so, then how might it be done?
Yes I agree with Lin. Simply reflect "A" over an line between "A" and "B"
Yes I agree with Lin. First Polygon A is reflected over a vertical line that passes the right edge of "A" and the left edge of "B". Then that image is reflected over a horizontal line that passes the through the bottom of "A" and the top of "B". This will give the image of "B".
I do not agree with Lin. These are different sized images and so "A" cannot map to "B".

Are two rectangles with the same side lengths always congruent?
No, if I traced with patty paper, they would not be the same.
No, just because the side lengths are the same doesn't mean that the angles are the same.
Yes, all rectangles have 90° angles. So, if I know that the side lengths and angles are the same, then they must be congruent.
No, if it's turned differently, then they can't be congruent.
