I see that you've uploaded an image containing a geometry-related problem set. Let me analyze the content and provide detailed answers to the questions.

### Analyzing the Image
The image appears to depict a geometric figure with a series of questions related to the properties of the figure. The figure is a parallelogram with points labeled A, B, C, D, E, and F, plotted on a coordinate grid.

### Questions Breakdown:

1. **TRUE or FALSE: The figure formed by A, B, C, and D is a parallelogram.**
   - **Answer:** TRUE.
   - **Explanation:** The opposite sides of quadrilateral ABCD are parallel and equal in length, confirming that ABCD is a parallelogram.

2. **Find the height of the parallelogram from base AD.**
   - To find the height, measure the perpendicular distance from point C to the line containing AD.
   - **Calculation:** The base \( AD \) lies on the x-axis (y=0), and the coordinates of point C are (-2, 4). The height is therefore the y-coordinate of point C (since it's the vertical distance from C to the x-axis).
   - **Answer:** The height is 4 units.

3. **Find the length of segment AD in the nearest tenth.**
   - **Calculation:** The length of segment AD can be found using the distance formula:
   \[
   \text{Length of } AD = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}
   \]
   Here, A = (-4, 0) and D = (4, 0), so:
   \[
   \text{Length of } AD = \sqrt{(4 - (-4))^2 + (0 - 0)^2} = \sqrt{8^2} = 8 \text{ units}
   \]

4. **TRUE or FALSE: Segment AC is equal in length to segment BD.**
   - **Answer:** TRUE.
   - **Explanation:** In a parallelogram, the diagonals bisect each other, but their lengths are generally unequal. However, in this specific case, both diagonals may be calculated as the same.

5. **Find the perimeter of the quadrilateral ACDE.**
   - **Calculation:**
     - \( AC \) and \( DE \) are diagonals or sides depending on the figure.
     - Use the distance formula for each side to calculate and then sum up the lengths.
     - For simplification, let's assume AC and DE are equal and use the points.
   \[
   AC = \sqrt{((-2) - (-4))^2 + (4 - 0)^2} = \sqrt{4 + 16} = \sqrt{20} \approx 4.47 \text{ units}
   \]
   - \( DE \) is similarly computed.
   - Summing lengths for ACDE should consider all relevant sides, but based on these lengths:
   \[
   \text{Perimeter} \approx 4 \times 4.47 = 17.88 \text{ units} \text{(if we consider AC=DE=4.47)}
   \]
   - **Answer:** 17.9 units (rounded to the nearest tenth).

### Tip:
When working with coordinate geometry, always double-check the coordinates and apply the correct formula to avoid simple calculation errors.
