To find the lines of reflection that will flip the quadrilateral ABCD onto itself, we can analyze the coordinates of the vertices:
- A(-4, 3)
- B(5, 3)
- C(5, -2)
- D(-4, -2)
### Step 1: Identify the midpoints
We can find the midpoints of opposite sides to help identify the lines of symmetry.
For side AB:
- Midpoint (M1) = \(\left(\frac{-4 + 5}{2}, \frac{3 + 3}{2}\right) = \left(\frac{1}{2}, 3\right)\)
For side CD:
- Midpoint (M2) = \(\left(\frac{5 + -4}{2}, \frac{-2 + -2}{2}\right) = \left(\frac{1}{2}, -2\right)\)
The midpoint between AB and CD can be seen to be directly vertical. There will be a line of reflection at \(x = 0.5\) (the average of the x-coordinates of the midpoints of AB and CD).
### Step 2: Find the additional line of reflection
Next, we look at the midpoints of sides AD and BC:
For side AD:
- Midpoint (M3) = \(\left(\frac{-4 + -4}{2}, \frac{3 + -2}{2}\right) = (-4, \frac{1}{2})\)
For side BC:
- Midpoint (M4) = \(\left(\frac{5 + 5}{2}, \frac{3 + -2}{2}\right) = (5, \frac{1}{2})\)
This indicates a line of reflection that is horizontal, which will be found directly between the y-coordinates of M3 and M4. Since both midpoints share the same \(y\) coordinate, the midpoint is at \(y = 0.5\).
### Final Lines of Reflection
Thus, we conclude that the lines of reflection for the quadrilateral that will flip it onto itself are:
- \(x = \frac{1}{2}\)
- \(y = \frac{1}{2}\)
#### Answer:
The lines of reflection are:
\(x = \frac{1}{2}\) and \(y = \frac{1}{2}\).
- A(-4, 3)
- B(5, 3)
- C(5, -2)
- D(-4, -2)

Apologies for any confusion. Yes, \(0.5\) is the decimal representation of \(\frac{1}{2}\).
So, the lines of reflection can be expressed as:
- \(x = 0.5\)
- \(y = 0.5\)
To summarize:
The lines of reflection are:
- \(x = 0.5\)
- \(y = 0.5\)
Both values are equivalent, just expressed in different forms (fraction vs. decimal). Thank you for your patience!
