The image presents four pairs of figures, and it asks which pairs are **congruent** and which pairs are **similar**.

- **Congruent figures** are identical in both shape and size, meaning they can be transformed into each other through translation, rotation, or reflection.
- **Similar figures** have the same shape but can differ in size, meaning they are proportional.

Let’s evaluate each pair:

1. **Top-left (Two squares)**:
   - These squares appear to be the same shape but different sizes.
   - **Congruent?** No, because they are not the same size.
   - **Similar?** Yes, because they have the same shape but are scaled versions of each other.

2. **Top-right (Two triangles)**:
   - These triangles have different shapes and sizes.
   - **Congruent?** No, because they are not the same shape or size.
   - **Similar?** No, because they are not the same shape.

3. **Bottom-left (Two ovals)**:
   - These appear to be ovals of different sizes.
   - **Congruent?** No, because the sizes are different.
   - **Similar?** Yes, because the shapes are the same (both are ovals) but scaled differently.

4. **Bottom-right (Two abstract shapes)**:
   - The shapes are identical in form and size.
   - **Congruent?** Yes, because they are the same size and shape.
   - **Similar?** Yes, because congruent figures are also similar.

Summary:
- **Top-left (squares)**: Congruent? No, Similar? Yes
- **Top-right (triangles)**: Congruent? No, Similar? No
- **Bottom-left (ovals)**: Congruent? No, Similar? Yes
- **Bottom-right (abstract shapes)**: Congruent? Yes, Similar? Yes

Let me know if you'd like further details or clarifications! 

Here are five follow-up questions:
1. What transformations preserve congruence?
2. Can two figures be similar but not congruent?
3. How do you calculate the scale factor between two similar shapes?
4. What are examples of congruent shapes in geometry?
5. How does rotation or reflection affect congruence?

**Tip:** Always remember, congruent shapes are also similar, but similar shapes are not necessarily congruent.

Which pairs of figures are congruent? Which pairs are similar?

This problem asks students to determine which pairs of geometric figures are congruent and which are similar. It explores core concepts of congruence and similarity, applicable for students in Grades 6-8. Key knowledge points include geometric shapes, the congruence theorem, and similarity theorem.
