Grade 8. This describes the skill, not a learner estimate.
What slides, flips, and turns keep the same
Verify by measuring that slides, flips and turns keep lengths, angles and parallel lines
Problem types
- Measure before and after a slide, flip or turn
- What must stay true after a slide, flip or turn
- Find the figure that could be the image
- Decide whether a figure could be the image
Builds on
Leads to
- Dilations and similarity · Extend the idea
Slides, flips and turns keep every length, every angle and every pair of parallel lines. A dilation keeps the angles and the parallel lines too, but it multiplies every length by the scale factor.
