8.G - Geometry Domain



GEOMETRY DOMAIN

  • 8.G.1 -  Verify experimentally the properties of rotations, reflections, and translations:
  • 8.G.1a -  Lines are taken to lines, and line segments to line segments of the same length.
  • 8.G.1b -  Angles are taken to angles of the same measure.
  • 8.G.1c -  Parallel lines are taken to parallel lines.

  • 8.G.2  - Understand that a two-dimensional figure is congruent to another if the second can be obtained from the first by a sequence of rotations, reflections, and translations; given two congruent figures, describe a sequence that exhibits the congruence between them.
  • 8.G.3 -  Describe the effect of dilations, translations, rotations, and reflections on two-dimensional figures using coordinates.
  • 8.G.4  - Understand that a two-dimensional figure is similar to another if the second can be obtained from the first by a sequence of rotations, reflections, translations, and dilations; given two similar two-dimensional figures, describe a sequence that exhibits the similarity between them.

 

Solving Similar Triangles with Proportions

 

 

  • 8.G.6 -  Explain a proof of the Pythagorean Theorem and its converse.
  • 8.G.7 -  Apply the Pythagorean Theorem to determine unknown side lengths in right triangles in real-world and mathematical problems in two and three dimensions.
