Contenido principal

## 8.G.A.1

Verify experimentally the properties of rotations, reflections, and translations:

## 8.G.A.1a

Lines are taken to lines, and line segments to line segments of the same length.

## 8.G.A.1b

Angles are taken to angles of the same measure.

## 8.G.A.1c

Parallel lines are taken to parallel lines.

## 8.G.A.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.A.3

Describe the effect of dilations, translations, rotations, and reflections on two-dimensional figures using coordinates.

## 8.G.A.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.

## 8.G.A.5

Use informal arguments to establish facts about the angle sum and exterior angle of triangles, about the angles created when parallel lines are cut by a transversal, and the angle-angle criterion for similarity of triangles.

## 8.G.B.6

Explain a proof of the Pythagorean Theorem and its converse.
