Introduction

Understanding the Concept of Rectangles

A rectangle is a fundamental geometric shape that holds unique properties. It is a polygon with four sides, four angles, and opposite sides that are parallel and equal in length. Rectangles are commonly encountered in various aspects of mathematics and everyday life due to their regular and predictable nature.

Definition of a Rectangle

A rectangle is defined as a quadrilateral (a polygon with four sides) with the following characteristics:

  • Four right angles: Each angle within a rectangle measures 90 degrees, making it a right angle.
  • Opposite sides are parallel: The two pairs of opposite sides in a rectangle are parallel to each other.
  • Opposite sides are equal in length: The lengths of the two pairs of opposite sides are equal.

Analyzing the Given Points

Point 1: (4, 1)

Let's begin our analysis by looking at the first point provided: (4, 1).

Coordinates and Representation

The coordinates (4, 1) represent a point in a two-dimensional Cartesian plane. The first number, 4, indicates the horizontal position of the point along the x-axis, while the second number, 1, indicates its vertical position along the y-axis.

Geometric Interpretation

When we plot the point (4, 1) on a graph, we find it located 4 units to the right of the origin (x-axis) and 1 unit above the origin (y-axis). This point serves as one of the vertices of the figure in question.

Point 2: (2, 4)

Moving on to the second point: (2, 4).

Coordinates and Representation

The coordinates (2, 4) also represent a point in the two-dimensional Cartesian plane. The first number, 2, indicates the horizontal position of the point along the x-axis, and the second number, 4, indicates its vertical position along the y-axis.

Geometric Interpretation

When plotted on a graph, the point (2, 4) is located 2 units to the right of the origin and 4 units above it. This point forms another vertex of the figure we are examining.

Point 3: (4, 0)

Let's now analyze the third point: (4, 0).

Coordinates and Representation

The coordinates (4, 0) place this point on the Cartesian plane. The first number, 4, represents its horizontal position along the x-axis, and the second number, 0, represents its vertical position along the y-axis.

Geometric Interpretation

When we plot the point (4, 0), it falls 4 units to the right of the origin and lies exactly on the x-axis. This point contributes to defining the shape in question.

Point 4: (2, 3)

Lastly, we need to examine the fourth point: (2, 3).

Coordinates and Representation

The coordinates (2, 3) are indicative of a point in two-dimensional space. The first coordinate, 2, specifies its horizontal position along the x-axis, while the second coordinate, 3, specifies its vertical position along the y-axis.

Geometric Interpretation

When graphed, the point (2, 3) is situated 2 units to the right of the origin and 3 units above it. This point completes the set of vertices under consideration.
