Explore Activity 1
Exploring Rotations
Question 1. Communicate Mathematical Ideas How are the size and the orientation of the triangle affected by the rotation? Answer: A rotation is a transformation that turns a figure around a given point called the center of rotation. The image has the same size and shape as the preimage, but a different orientation. For example, the side \(\overline{\mathrm{BC}}\) was vertical and on the image, it will be horizontal.

Properties of Rotations
Question 3. Make a Conjecture Use your results from E, H, and I to make a conjecture about rotations. Answer: The image of a figure and its preimage have the same length of sides and the same interior angles, which means that the two figures are congruent.
Question 4. Place your tracing back in its original position. Then perform a 180° clockwise rotation about the origin. Compare the results. Answer: The image will be the same after a 180° clockwise rotation and after a 180° counterclockwise rotation.
Question 7. 270° clockwise Answer: Step 1: Rotate the figure clockwise from the y-axis to the x-axis. Point A will still be at (0,0). Plot point B”(-2, 1). Plot point C”(-2, 4). Plot point D”(0, 3).
Question 8. Find the coordinates of Point C after a 90° counterclockwise rotation followed by a 180° rotation. Answer: The coordinates of point C after a 90° counterclockwise rotation followed by a 180° rotation are (2, -4).

Siobhan rotates a right triangle 90° counterclockwise about the origin.
Question 2. How does the orientation of the image of the triangle compare with the orientation of the preimage? (Explore Activity 1) Answer: The image has the same size and shape as the preimage. but different orientations.
Lesson 12.3 Rotations Answer Key Go Math 8th Grade Question 3. Is the image of the triangle congruent to the preimage? (Explore Activity 2) Answer: The image of the figure and its preimage have the same size and shape, so this means that the two figures are congruent.
Draw the image of the figure after the given rotation about the origin. (Example 1)
Essential Question Check-In
Question 6. What are the properties of rotations? Answer: The image and its preimage have the same size and shape, but different orientation.
Texas Go Math Grade 8 Lesson 12.3 Independent Practice Answer Key
b. What are the coordinates of the image? Answer: The coordinates of the image are: A'(3, 1), B'(2, 3) and C'(-1, 4).
b. Can you describe this as a transformation other than a rotation? Explain. Answer: Yes, this transformation also can be a reflection across the y-axis.
Question 10. A point with coordinates (-2, -3) is rotated 90° clockwise about the origin. What are the coordinates of its image? Answer: The coordinates of its image are (-3, 2).
Complete the table with rotations of 180° or less. Include the direction of rotation for rotations of less than 180°.
Activity 12.3 Rotations 8th Grade Math Answer Key Pdf Question 12.
Draw the image of the figure after the given rotation about the origin.
Question 16. Is there a rotation for which the orientation of the image is always the same as that of the preimage? If so, what? Answer: Yes, there is 360° rotation With that rotation the orientation of the image is always the same as that of the preimage.
H.O.T. Focus on Higher Order Thinking
Texas Go Math Grade 8 Pdf Rotation Answer Key Question 18. Make a Conjecture Triangle ABC is reflected across the y-axis to form the image A’B’C’. Triangle A’B’C’ is then reflected across the x-axis to form the image A”B”C”. What type of rotation can be used to describe the relationship between triangle A”B”C” and triangle ABC? Answer: Triangle A’B’C’ is a 90° rotation of triangle ABC Triangle A”B”C” is a 90° rotation of triangle A’B’C’. Therefore, Triangle A”B”C” is a 180° rotation of triangle ABC

Question 5. the height of a flagpole _________ Answer: the height of a flagpole length.
Question 6. A box is 5 inches long, 4 inches wide, and 1 inch deep. How much space is inside the box? Answer: The space inside the box is 20 cubic in.
Explanation: Given that a box is 5 inches long, 4 inches wide, and 1 inch deep, so the space inside the box is 5 × 4 × 1 which is 20 cubic in.
Question 7. Aponi built a toy chest for her niece. It has a volume of 12 cubic feet. The chest is 3 feet long and 2 feet wide. How deep is it? Answer: The depth of the chest is 2 ft.
Explanation: Given that Aponi built a toy chest for her niece. It has a volume of 12 cubic feet. The chest is 3 feet long and 2 feet wide. So the depth of the toy chest is, let the depth be h 12 = 3 × 2 × h 12 = 6 × h h = 12 ÷ 6 = 2 ft.
Question 8. The rug in Alan’s room has an area of 18 square feet. He is planning to buy another rug that is twice as long and twice as wide. What is the area of the new rug? Answer: The area of the new rug is 72 square feet.
Explanation: Given that the rug in Alan’s room has an area of 18 square feet, so the possible length and the wide of the rug will be 3 ft long and 6 ft wide. And he is planning to buy another rug that is twice as long and twice as wide, so the length will be 6 ft long and the wide will be 12 ft. So the area of the new rug will be 6 × 12 which is 72 square feet.
Question 9. Each drawer in Monique’s nightstand has a volume of 6 cubic decimeters. Each drawer in her dresser is twice as long, twice as wide, and twice as deep. What is the volume of one of Monique’s dresser drawers? Answer:
Explanation: In the above figure, Fong has 6 × 5 × 3 which has 90 cubes and Daphne has 5 × 4 × 4 which has 80 cubes. So Fong used more 90 – 80 which is 10 cubes more.
