UP:MA19.8.22
Vocabulary
- Congruent
- Rotation
- Reflection
- Translation
Knowledge
Students know:
- How to measure line segments and angles.
- That similar figures have congruent angles.
- The definition/concept of what a figure does when it undergoes a rotation, reflection, and translation.
- How to perform a translation, reflection, and rotation.
Skills
Students are able to:
- verify by measuring and comparing lengths of a figure and its image that after a figure has been translated, reflected, or rotated its corresponding lines and line segments remain the same length.
Understanding
Students understand that:
- congruent figures have the same shape and size.
- Two figures in the plane are said to be congruent if there is a sequence of rigid motions that takes one figure onto the other.
