Answer:

a 90° clockwise rotation about the origin and a reflection across the x-axis

Step-by-step explanation:

A 90° counterclockwise rotation about the origin means a right angle about the origin in opposite direction the needle would point to (9=45 mins)the reflection of it would mean the needle is at 3 = 15 min

Yes shape I is congruent to shape II because on both shape the needle lies on the x- axis.

a reflection across the y-axis and a 90° clockwise rotation about the origin

  • No because at one end the needle is at 3 and at the other the needle is at 9 giving a difference of negative and positive quadrants

a 90° counterclockwise rotation about the origin and a reflection across the y-axis

  • No because at one end the needle is at 9 and at the other the needle is at 3 giving a difference of negative and positive quadrants

a 90° counterclockwise rotation about the origin

  • It shows 3/4 of the sphere

a 90° clockwise rotation about the origin and a reflection across the x-axis

  • Yes because the needle lies on the x- axis at both ends

a 90° clockwise rotation about the origin

  • It shows 1/4 of the sphere.
