# Lesson 3 – Complementary, Supplementary, & Vertical Angles

# Lesson 4 – Transversals, Parallel Lines, and Angle Relationships

# Lesson 5 – Triangles: Their Sides and Angles

# Lesson 6 – Introduction to Polygons

This chapter takes you through the fundamentals of geometry! You will begin learning about the building blocks of geometry and how to label and classify them. Then you are off to rocking complementary, supplementary, and vertical angles before discovering the magic behind parallel lines and transversals! A thorough introduction to triangles, polygons, and congruent figures follows. The key parts of circles, circumference and circle graphs is then explored. You will finish off the chapter with the study of three types of transformations: translations, reflections, and rotations. Time to shape up and learn some geometry!!!
