The question in the image asks about the type of quadrilateral formed by the points $(6, 1)$, $(1, -1)$, $(2, -7)$, and $(-3, -3)$. Let's determine the type of quadrilateral by calculating the lengths of its sides and diagonals, as well as checking if any of the sides are parallel.

First, we label the points:

• $A = (6, 1)$
• $B = (1, -1)$
• $C = (2, -7)$
• $D = (-3, -3)$

We will calculate the distances between consecutive points $AB$, $BC$, $CD$, and $DA$ as well as the diagonals $AC$ and $BD$.

Step 1: Calculate the distances

The distance between two points $(x_1, y_1)$ and $(x_2, y_2)$ is given by: $d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

Let's calculate each of these distances now.The lengths of the sides and diagonals of the quadrilateral are as follows:

• $AB = 5.39$ (approx.)
• $BC = 6.08$ (approx.)
• $CD = 6.40$ (approx.)
• $DA = 9.85$ (approx.)
• Diagonal $AC = 8.94$ (approx.)
• Diagonal $BD = 4.47$ (approx.)

Since all the sides are of different lengths, the quadrilateral is not a square, rectangle, rhombus, or parallelogram. Additionally, the diagonals have different lengths, confirming that it is not any special parallelogram.

Therefore, this quadrilateral is a general irregular quadrilateral.

Here are 5 follow-up questions to expand on this information:

1. How do we verify if a quadrilateral is a parallelogram using its sides and diagonals?
2. How can we check if a quadrilateral is a trapezoid?
3. What role do slopes play in determining the type of quadrilateral?
4. How can we calculate the area of an irregular quadrilateral using these points?
5. How would the classification change if one pair of opposite sides were parallel?

Tip: Always verify whether opposite sides are parallel by comparing their slopes when determining the type of quadrilateral.
