Link Sheet is a useful tool. It looks as below:

Concept:
Mathematics (Symbol)	Everyday Example
Diagram/Picture/Graph	My Explanation

This tool can be used

Correct option is B

The tool described focuses on using everyday examples, diagrams, and explanations, which is key in exploring the concepts of similarity. It moves beyond just checking prior knowledge or proving theorems and instead focuses on engaging students with visual aids and relatable examples to deepen their understanding of similarity.
Information Booster:
1. Similarity refers to when two shapes are the same shape but may differ in size.
2. Exploring similarity often involves comparing side ratios and angles.
3. Visual representations, like diagrams or graphs, are essential in understanding geometric concepts.
4. Everyday examples help students relate abstract mathematical ideas to real-world situations.
5. Congruency involves shapes being identical in both shape and size, while similarity allows for proportional differences.
6. The Basic Proportionality Theorem, also known as Thales' theorem, is an important concept in triangle similarity.
Additional Information:
· (a) to introduce the topic on Similarity, for checking the previous knowledge of Congruency: This might be useful but is a preliminary step, not the tool's main purpose.
· (b) to explore the concepts of Similarity: This aligns best with the described tool, focusing on discovery and understanding of similarity.
· (c) to build the basis for theorems in Similar Triangles: While the tool could help, it does not seem primarily designed for theorem development.
· (d) to assess the understanding of Basic Proportionality Theorem: Assessment usually involves testing knowledge rather than using exploratory tools like the one shown.
