Angles and Figures
Content Objective:
- 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.
- 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.
- 8.G.B.8 - Apply the Pythagorean Theorem to find the distance between two points in a coordinate system.
