Chapter 5: Congruence, Enlargement and Combined Transformation
What you need to learn in this chapter
In this chapter, we will be learning about congruency, enlargement, combined transformation, and tessellation. We will learn how to differentiate between congruent and non-congruent shapes based on their sides and angles. We will also learn how to make and verify conjectures about triangle congruency based on their sides and angles. Additionally, we will explore enlargement, which involves changing the size of a shape while maintaining its shape and proportions. Lastly, we will study combined transformations, where we will learn how to perform multiple transformations on a shape.
Topics in this chapter
1. Congruency
What you will learn in this topic
- Differentiate between congruent and noncongruent shapes based on sides and angles.
