### CCSS.MATH.CONTENT.8.G.A.1

This course contains materials aligned to the 8th Grade Math Common Core Standard CCSS.MATH.CONTENT.8.G.A.1. Verify experimentally the properties of rotations, reflections, and translations:

### CCSS.MATH.CONTENT.8.G.A.1...

This course contains materials aligned to the 8th Grade Math Common Core Standard CCSS.MATH.CONTENT.8.G.A.1.A Lines are taken to lines, and line segments to line segments of the same length.

### CCSS.MATH.CONTENT.8.G.A.1...

This course contains materials aligned to the 8th Grade Math Common Core Standard CCSS.MATH.CONTENT.8.G.A.1.B Angles are taken to angles of the same measure.

### CCSS.MATH.CONTENT.8.G.A.2

This course contains materials aligned to the 8th Grade Math Common Core Standard CCSS.MATH.CONTENT.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.

### CCSS.MATH.CONTENT.8.G.A.5

This course contains materials aligned to the 8th Grade Math Common Core Standard CCSS.MATH.CONTENT.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. For example, arrange three copies of the same triangle so that the sum of the three angles appears to form a line, and give an argument in terms of transversals why this is so.

### CCSS.MATH.CONTENT.8.G.B.6

This course contains materials aligned to the 8th Grade Math Common Core Standard CCSS.MATH.CONTENT.8.G.B.6. Explain a proof of the Pythagorean Theorem and its converse.

### CCSS.MATH.CONTENT.8.G.B.7

This course contains materials aligned to the 8th Grade Math Common Core Standard CCSS.MATH.CONTENT.8.G.B.7. Apply the Pythagorean Theorem to determine unknown side lengths in right triangles in real-world and mathematical problems in two and three dimensions.
