Looking at the image, you have a set of three triangles on a coordinate grid. One of them is a rotation of triangle ABC, and the other is a reflection.

Let's solve the questions one by one:

### 1. **Which triangle is the rotation of triangle ABC?**
The rotation of triangle ABC will have the same orientation (no flipping) but rotated around a point. 

- The green triangle, located in the second quadrant, maintains the same orientation as triangle ABC but appears rotated. It is likely a 90-degree counterclockwise rotation.
  
**Answer**: The green triangle is the rotation of triangle ABC.

**a. What is the center of rotation?**
- A 90-degree rotation typically occurs around the origin (0, 0). By checking the coordinates of the points, we can see that a 90-degree counterclockwise rotation of triangle ABC around the origin will match the location of the green triangle.

**Answer**: The center of rotation is the origin (0, 0).

### 2. **Which triangle is the reflection of triangle ABC?**
The reflection of triangle ABC will appear flipped, and the shape will be mirrored across an axis.

- The red triangle, located below the x-axis, is a mirror image of triangle ABC, indicating it is the reflection.

**Answer**: The red triangle is the reflection of triangle ABC.

**a. Which axis is the line of reflection?**
- Since triangle ABC and the red triangle appear mirrored across the x-axis (the horizontal line), the reflection occurs across the x-axis.

**Answer**: The line of reflection is the x-axis.

Would you like more details on how to perform geometric transformations? Here are 5 related questions to deepen your understanding:

1. How do you calculate the coordinates of a point after a 90-degree counterclockwise rotation around the origin?
2. What are the steps to reflect a point over the x-axis?
3. How do you determine the center of rotation for any given transformation?
4. How does a 180-degree rotation differ from a 90-degree rotation geometrically?
5. Can a reflection occur over an arbitrary line, like \(y = x\)? How does it change the coordinates?

**Tip**: Always check the orientation of triangles when identifying rotations or reflections; rotations preserve orientation, while reflections reverse it.

One of the triangles pictured is a rotation of triangle ABC and one of them is a reflection. 1. Which triangle is the rotation of ABC? a. What is the center of rotation? 2. Which triangle is the reflection of ABC? a. Which axis is the line of reflection?
