Introduction

Higher order thinking is a critical component of mathematics education, enabling students to move beyond mere memorization and calculation to a deeper understanding of mathematical concepts. In this article, we will explore the concept of higher order thinking in mathematics, with a focus on geometric transformations. We will examine a problem involving the vertices of a pentagon and its image under a series of transformations, demonstrating the application of higher order thinking skills in mathematics.

What is Higher Order Thinking?

Higher order thinking refers to the ability to analyze, evaluate, and create complex ideas and solutions. In mathematics, higher order thinking involves more than just recalling formulas and procedures; it requires the ability to understand the underlying concepts and principles, and to apply them in a variety of contexts. Higher order thinking skills include:

Analysis: Breaking down complex information into smaller parts to understand the relationships between them.
Evaluation: Making informed judgments about the validity and reliability of information.
Creation: Generating new ideas and solutions to problems.
Application: Using mathematical concepts and principles to solve real-world problems.

Geometric Transformations

Geometric transformations are a fundamental concept in mathematics, involving the movement or transformation of geometric shapes from one position to another. There are several types of geometric transformations, including:

Translation: Moving a shape from one position to another without changing its size or orientation.
Rotation: Rotating a shape around a fixed point or axis.
Reflection: Flipping a shape over a line or plane.
Dilation: Enlarging or reducing a shape by a scale factor.

Problem: The Vertices of a Pentagon

The vertices of a pentagon ${$ V W X Y Z$}$ are ${$ V(4,5), W(6,5), X(6,7), Y(5,8),$}$ and ${$ Z(4,7)$}$. The pentagon is transformed by a series of translations, rotations, and reflections. We are asked to find the image of the pentagon under these transformations.

Step 1: Translation

The pentagon is translated 2 units to the right and 3 units up. This means that each vertex of the pentagon is moved 2 units to the right and 3 units up.

Step 2: Rotation

The translated pentagon is rotated 90 degrees counterclockwise around the origin. This means that each vertex of the translated pentagon is rotated 90 degrees counterclockwise around the origin.

Step 3: Reflection

The rotated pentagon is reflected over the x-axis. This means that each vertex of the rotated pentagon is reflected over the x-axis.

Step 4: Dilation

The reflected pentagon is dilated by a scale factor of 2. This means that each vertex of the reflected pentagon is enlarged or reduced by a scale factor of 2.

Solution

To find the image of the pentagon under these transformations, we need to apply each transformation in sequence.

Step 1: Translation

The vertices of the translated pentagon are:

${$ V^{\prime}(4+2,5+3)=(6,8)$}$
${$ W^{\prime}(6+2,5+3)=(8,8)$}$
${$ X^{\prime}(6+2,7+3)=(8,10)$}$
${$ Y^{\prime}(5+2,8+3)=(7,11)$}$
${$ Z^{\prime}(4+2,7+3)=(6,10)$}$

Step 2: Rotation

The vertices of the rotated pentagon are:

${$ V^{\prime\prime}(-8,6)$}$
${$ W^{\prime\prime}(-8,8)$}$
${$ X^{\prime\prime}(-10,10)$}$
${$ Y^{\prime\prime}(-11,7)$}$
${$ Z^{\prime\prime}(-10,6)$}$

Step 3: Reflection

The vertices of the reflected pentagon are:

${$ V^{\prime\prime\prime}(-8,-6)$}$
${$ W^{\prime\prime\prime}(-8,-8)$}$
${$ X^{\prime\prime\prime}(-10,-10)$}$
${$ Y^{\prime\prime\prime}(-11,-7)$}$
${$ Z^{\prime\prime\prime}(-10,-6)$}$

Step 4: Dilation

The vertices of the dilated pentagon are:

${$ V^{\prime\prime\prime\prime}(-16,-12)$}$
${$ W^{\prime\prime\prime\prime}(-16,-16)$}$
${$ X^{\prime\prime\prime\prime}(-20,-20)$}$
${$ Y^{\prime\prime\prime\prime}(-22,-14)$}$
${$ Z^{\prime\prime\prime\prime}(-20,-12)$}$
