Mathematics | Course : Model Geometry (Traditional Pathway)

Domain - Similarity, Right Triangles, and Trigonometry

Cluster - Understand similarity in terms of similarity transformations.

[GEO.G-SRT.A.1.b] - The dilation of a line segment is longer or shorter in the ratio given by the scale factor.

Resources:


  • Dilation
    A transformation that moves each point along the ray through the point emanating from a fixed center, and multiplies distances from the center by a common scale factor.

Predecessor Standards:

  • 8.G.A.3
    Describe the effect of dilations, translations, rotations, and reflections on two-dimensional figures using coordinates.

Successor Standards:

No Successor Standards found.

Same Level Standards:

  • GEO.G-SRT.A.1.a
    A dilation takes a line not passing through the center of the dilation to a parallel line, and leaves a line passing through the center unchanged.
