Module 2

This course is a part of 8th grade (Eureka Math/EngageNY), a 7-course Topic series from Khan Academy.

"In Module 2, students study congruence by experimenting with rotations, reflections, and translations of geometrical figures. Their study of congruence culminates with an introduction to the Pythagorean Theorem in which the teacher guides students through the “square-within-a-square” proof of the theorem. Students practice the theorem in real-world applications and mathematical problems throughout the year." Eureka Math/EngageNY (c) 2015 GreatMinds.org

This course contains 4 segments:

Topic A: Definitions and properties of the basic rigid motions

Topic A includes lessons 1-6 and covers definition of translation and three basic properties, translating lines, definition of reflection and basic properties, definition of rotation and basic properties, and rotations of 180 degrees. (Currently, we do not have content for Lesson 1.)

Topic B: Sequencing the basic rigid motions

Topic B includes lessons 7-10 and covers sequencing translations, sequencing reflections and translations, sequencing rotations, and sequences of rigid motions.

Topic C: Congruence and angle relationships

Topic C includes lessons 11-14 and covers definition of congruence and some basic properties, angles associated with parallel lines, angle sum of a triangle, and more on the angles of a triangle.

Topic D: The Pythagorean theorem

Topic D includes lessons 15-16 and covers informal proof of the Pythagorean theorem and applications of the Pythagorean theorem.
