Introduction

In geometry, a quadrilateral is a four-sided polygon. When given the coordinates of its vertices, we can use various methods to classify it into different types, such as squares, rhombuses, rectangles, and more. In this article, we will explore how to classify a quadrilateral with vertices at the points $(0,0), (-1,4), (4,0), (4,4)$.

Graphing the Points

To start, let's graph the given points on a coordinate plane. We can use the distance formula to find the lengths of the sides of the quadrilateral.

Distance Formula

The distance formula is given by:

$$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$$

We can use this formula to find the lengths of the sides of the quadrilateral.

Finding the Lengths of the Sides

Let's find the lengths of the sides of the quadrilateral using the distance formula.

• Side 1: From $(0,0)$ to $(-1,4)$

  $$d_1=\sqrt{(-1-0)^2+(4-0)^2}=\sqrt{1+16}=\sqrt{17}$$

• Side 2: From $(-1,4)$ to $(4,0)$

  $$d_2=\sqrt{(4-(-1))^2+(0-4)^2}=\sqrt{25+16}=\sqrt{41}$$

• Side 3: From $(4,0)$ to $(4,4)$

  $$d_3=\sqrt{(4-4)^2+(4-0)^2}=\sqrt{0+16}=4$$

• Side 4: From $(4,4)$ to $(0,0)$

  $$d_4=\sqrt{(0-4)^2+(0-4)^2}=\sqrt{16+16}=\sqrt{32}=4\sqrt{2}$$

Analyzing the Results

Now that we have found the lengths of the sides of the quadrilateral, let's analyze the results.

• Side 1: $\sqrt{17}$
• Side 2: $\sqrt{41}$
• Side 3: $4$
• Side 4: $4\sqrt{2}$

We can see that the lengths of the sides are not equal, which means that the quadrilateral is not a square.

Conclusion

Based on the analysis, we can conclude that the quadrilateral with vertices at the points $(0,0), (-1,4), (4,0), (4,4)$ is not a square. However, we can still classify it into other types of quadrilaterals.

Classification

A quadrilateral is a rhombus if all its sides are of equal length. However, in this case, the lengths of the sides are not equal. Therefore, the quadrilateral is not a rhombus.

However, we can see that the quadrilateral has two pairs of opposite sides that are equal in length. This means that the quadrilateral is a parallelogram.

Types of Parallelograms

A parallelogram can be classified into different types, such as rectangles, rhombuses, and squares. However, in this case, the quadrilateral is not a rectangle or a square.

Final Conclusion

Based on the analysis, we can conclude that the quadrilateral with vertices at the points $(0,0), (-1,4), (4,0), (4,4)$ is a parallelogram, but not a rectangle or a square.

Answer

The correct classification of the quadrilateral is a parallelogram.

Discussion

This problem requires the use of the distance formula to find the lengths of the sides of the quadrilateral. It also requires the analysis of the results to classify the quadrilateral into different types.
