## ◂Math Worksheets and Study Guides Eighth Grade. Similarity and scale

### The resources above correspond to the standards listed below:

#### Utah Core Standards

UT.8.G. GEOMETRY (8.G)
Understand congruence and similarity using physical models, transparencies, or geometry software (Standards 8.G.1â€“5). Understand and apply the Pythagorean Theorem and its converse (Standards 8.G.6â€“8). Solve real-world and mathematical problems involving volume of cylinders, cones, and spheres (Standard 8.G.9).
8.G.1. Verify experimentally the properties of rotations, reflections, and translations:
8.G.1.a. Lines are taken to lines, and line segments to line segments of the same length.
8.G.1.b. Angles are taken to angles of the same measure.
8.G.1.c. Parallel lines are taken to parallel lines.
8.G.3. Observe that orientation of the plane is preserved in rotations and translations, but not with reflections. Describe the effect of dilations, translations, rotations, and reflections on two-dimensional figures using coordinates.
