Solution
To determine the series of transformations that move pentagon FGHIJ onto pentagon F’G’H’I’J’, we need to analyze the positions and orientations of both pentagons. Since the figures are congruent, we know that the transformations will preserve the size and shape of the pentagons.
Let's break down the steps:
-
Identify the initial and final positions: Look at the coordinates of the vertices of pentagon FGHIJ and compare them with the coordinates of pentagon F’G’H’I’J’. This will help us understand how the pentagon has been moved.
-
Check for translation: A translation moves every point of a shape the same distance in the same direction. If the pentagon FGHIJ has been shifted to a new location without changing its orientation, then a translation has occurred.
-
Check for reflection: A reflection flips the shape over a line, such as the x-axis or y-axis. If the pentagon appears to be a mirror image of its original position, then a reflection has occurred.
-
Check for rotation: A rotation turns the shape around a fixed point. If the pentagon has been rotated (clockwise or counterclockwise) to match the position of pentagon F’G’H’I’J’, then a rotation has occurred.
-
Determine the sequence: Sometimes, more than one transformation is needed. We need to determine the correct sequence of transformations that will move pentagon FGHIJ to pentagon F’G’H’I’J’.
Given the options:
- A. Translation, translation
- B. Reflection, rotation
- C. Translation, reflection
- D. Reflection, translation
Let's consider each option:
-
Option A (Translation, translation): This would involve moving the pentagon twice in different directions. This is unlikely unless the pentagon needs to be moved in two distinct steps, which is not common for simple congruent transformations.
-
Option B (Reflection, rotation): This would involve flipping the pentagon over a line and then rotating it. This is possible if the pentagon appears to be a mirror image and then rotated to match the final position.
-
Option C (Translation, reflection): This would involve moving the pentagon to a new location and then flipping it over a line. This is possible if the pentagon needs to be shifted and then mirrored.
-
Option D (Reflection, translation): This would involve flipping the pentagon over a line and then moving it to a new location. This is also possible if the pentagon needs to be mirrored first and then shifted.
To choose the correct option, we need to look at the specific coordinates and orientation of the pentagons. However, without the actual coordinates or a visual representation, we can make an educated guess based on common transformation sequences.
If the pentagon appears to be a mirror image and then shifted, Option D (Reflection, translation) is a likely choice. If the pentagon is shifted and then mirrored, Option C (Translation, reflection) is a likely choice.
Given the typical order of transformations, Option D (Reflection, translation) is often the correct sequence for moving a shape to a congruent position.
Therefore, the most likely answer is: D. Reflection, translation
