Question

1. what type of transformation is used to create a mirror image of a geometric figure? a. translation b. dilation c. reflection d. rotation 12. what do you call the point around which a figure is rotated? a. center of rotation b. vertex c. axis point d. pivot point 13. a figure looks the same after a rotation of 90 degrees. how many times does it exhibit rotational symmetry in a full turn? a. two b. one c. four d. three 14. which transformation involves sliding a figure from one position to another without rotating or flipping it? a. reflection b. rotation c. translation d. dilation 15. which transformation could be described as a slide of a figure along a straight path? a. rotation b. translation

Explanation:

1. Reflection creates mirror - images.
2. Center of rotation is the point of rotation.
3. A full - turn is 360 degrees, 360/90 = 4.
4. Translation is sliding a figure.
5. Sliding along a straight path is translation.

Answer:

1. c. Reflection
2. a. Center of rotation
3. c. Four
4. c. Translation
5. b. Translation
