**Exploration Activity**

**CRM 2.1 - Lesson 8**

*Measures?*

The image features a coordinate grid containing three triangles labeled with their vertices as follows:

1. **Triangle KLM**
   - K: (-6, -7)
   - L: (4, -7)
   - M: (2, -4)

2. **Triangle TUV**
   - T: (-2, -2)
   - U: (2, -2)
   - V: (0, 1)

3. **Triangle NOP**
   - N: (0, 0)
   - O: (2, 5)
   - F: (0, 2)

4. **Triangle GRS**
   - G: (7, 7)
   - R: (8, 4)
   - S: (9, 8.2)

**Tasks:**

- **a.** Describe the transformation that proves the triangles are congruent.
- **b.** List the congruent sides of the triangles.
- **c.** Use the distance formula to show that corresponding sides are congruent.

**Distance Formula:**

\[
\text{Distance} = \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2}
\]

The grid shows translations and reflected positions of triangles, allowing for the exploration of congruence through transformations such as translation, rotation, and reflection. Each triangle displays congruent properties through positional relationships on the grid, demonstrating congruence and similarity.
