**In Exercises 3-6, determine whether the coordinate plane shows a reflection in the x-axis, y-axis, or neither.**

**3) Description:**
- A coordinate plane with two triangles, labeled \(ABC\) in blue and \(DEF\) in red.
- Triangle \(ABC\) is located in the second quadrant. 
  - \(A\) at (-4, 2)
  - \(B\) at (-2, 4)
  - \(C\) at (-4, -2)
- Triangle \(DEF\) is located in the fourth quadrant.
  - \(D\) at (2, -4)
  - \(E\) at (4, -2)
  - \(F\) at (2, -6)

The red triangle is a reflection of the blue triangle across the y-axis.

**4) Description:**
- A coordinate plane with two triangles, labeled \(ABC\) in blue and \(DEF\) in red.
- Triangle \(ABC\) is located in the first quadrant.
  - \(A\) at (0, 1)
  - \(B\) at (2, 2)
  - \(C\) at (1, 4)
- Triangle \(DEF\) is located in the third quadrant.
  - \(D\) at (-2, -1)
  - \(E\) at (0, -2)
  - \(F\) at (-1, -4)

The red triangle is a reflection of the blue triangle across the x-axis.

The image is a coordinate grid displaying two right-angled triangles. The grid includes labeled axes: the horizontal axis (x-axis) and the vertical axis (y-axis), both marked with integers ranging from -4 to 4.

### Triangles:

1. **Triangle ABC (Blue):**
   - Vertex A is at the point (3, 0).
   - Vertex B is at the point (0, 0).
   - Vertex C is at the point (0, 3).
   - The triangle ABC is positioned in the first quadrant and is a right-angled triangle with the right angle at B.

2. **Triangle DEF (Red):**
   - Vertex D is at the point (-1, -2).
   - Vertex E is at the point (-3, -2).
   - Vertex F is at the point (-3, -4).
   - The triangle DEF is located in the third quadrant and is a right-angled triangle with the right angle at E.

This graph illustrates transformations on the coordinate plane, specifically focusing on the shifts and orientations of right-angled triangles in different quadrants.
