UP:MA19.8.23
Vocabulary
- Coordinates
- Congruent
- Rotation
- Reflection
- Translation
- Dilation
- Scale factor
Knowledge
Students know:
- What it means to translate, reflect, rotate, and dilate a figure.
- How to perform a translation, reflection, rotation, and dilation of a figure.
- How to apply (x, y) notation to describe the effects of a transformation.
Skills
Students are able to:
- Select and apply the proper coordinate notation/rule when given a specific transformation for a figure.
- Graph a pre-image/image for a figure on a coordinate plane when given a specific transformation or sequence of transformations.
Understanding
Students understand that:
- the use of coordinates is also helpful in proving the congruence/proportionality between figures.
- The relationships between coordinates of a preimage and its image for dilations represent scale factors learned in previous grade levels.
