standard_description: Verify experimentally the properties of rotations, reflections, and translations:
- Lines are taken to lines, and line segments to line segments of the same length.
- Angles are taken to angles of the same measure.
- Parallel lines are taken to parallel lines.
problem_activity: Identify the strategy that the student below used to find the measure of
$${BA}$$
. Then, describe a different method for finding this value, describing how you know that the two triangles are dilations of one another.
