Sure! Here are the answers to the questions based on your provided content:
-
Describe the translation below using words and then write a rule for it.
- A translation moves a shape in a specific direction by a certain distance. The rule for a translation can be expressed as \( (x, y) \rightarrow (x + a, y + b) \), where \( a \) and \( b \) are the horizontal and vertical distances moved, respectively.
-
Which shape below is the pre-image? How can you tell?
- The pre-image is the original shape before any transformation has taken place. You can identify it by looking for the shape that matches the description or set of coordinates provided before the transformation.
-
A pre-image and its image are congruent in which of the following transformations?
- Dilation: No (they are not congruent, only similar)
- Rotation: Yes
- Translation: Yes
- Reflection: Yes
Answer: Rotation, Translation, Reflection.
-
If the transformation below is performed, what would be the coordinates of point C'?
- Coordinates would depend on the transformation described. Without specific information, I cannot determine it, but if you provide the transformation, I can solve it.
-
If the transformation below is performed, what would be the coordinates of point Y'?
- If Triangle YQT is rotated 180 degrees about the origin, the coordinates of Y' would also need specific dimensions. If point Y has coordinates (x, y), after rotation it would become (-x, -y).
-
Describe how you would find the reflection point of D(-3,4) over the x-axis. You can use sentences to describe or draw a picture. What would be the coordinates of D'?
- To find the reflection point of D over the x-axis, you keep the x-coordinate the same and change the sign of the y-coordinate. Thus, D' would be (-3, -4).
-
Match each picture with the description.
- a. Rotation of 180 degrees about the origin
- b. Reflection over the line y = 1
- c. 90 Degree Rotation about the origin
- d. Translation left 2 and up 6
-
Which answer shows a reflection across the x-axis?
- A reflection across the x-axis would change (x, y) to (x, -y).
-
If Triangle B is rotated 270 degrees, what triangle would it land on?
- Assuming standard positions, a 270-degree rotation typically brings it to a position similar to Triangle A (or specific triangle placements based on given context).
-
What is the rule for the transformation below?
- The rule for the transformation represented by \( (x,y) \rightarrow (x+4, y-9) \) is: Translate right 4 and down 9.
-
If Pentagon PENTA is congruent to Pentagon ABCDE, choose all below that are true.
- The pentagons have the same shape and size. They could have been obtained from each other through transformations such as translation, rotation, or reflection.
- Which description below will take RPQ to ABC?
- Translate RPQ up 6 steps, then reflect it over the y-axis.
- Given the triangle ABC's coordinates below, what would be the coordinates of A'B'C' if it was dilated using a scale factor of 2?
- A' = (32, 42) = (6, 8)
- B' = (-32, 72) = (-6, 14)
- C' = (-12, 02) = (-2, 0)
- Coordinates of A'B'C' are (6,8), (-6,14), (-2,0).
- What is the name of the artist that used transformations to create patterns called Tessellations?
- M.C. Escher
- What is an example of a scale factor that would shrink a shape?
- A scale factor less than 1 (but greater than 0) would shrink a shape. (For example, 0.5 would shrink it by half.)
- What is the scale factor that was used to perform the dilation below?
- A scale factor can be determined based on the image provided. Without a visual reference, I can't determine which scale factor was used.
