NNAT Mirror Images and Rotations 3

Question 1

A rectangle is taller than it is wide. After a 90° clockwise rotation, what does it look like?

Accepted Answer

Wider than it is tall

Answer

Rotating 90° swaps the height and width, making the previously tall rectangle wider than tall.

Question 2

Which letter looks exactly the same when reflected across a vertical axis?

Accepted Answer

A

Answer

The letter 'A' has a vertical line of symmetry, so its mirror image looks identical.

Question 3

A shape has been rotated. The top of the shape now faces left. Which rotation was most likely applied?

Accepted Answer

90° counterclockwise

Answer

If the top now faces left, the shape was rotated 90° counterclockwise (turning it so its top swings to the left).

Question 4

Two mirror images of an asymmetric shape are placed side by side. Which statement is true?

Accepted Answer

They cannot be rotated to match each other

Answer

Mirror images of asymmetric shapes are non-superimposable; no rotation can make them match.

Question 5

A clock face is reflected in a vertical mirror. What time does the reflection show if the original shows 3:00?

Accepted Answer

9:00

Answer

Reflecting the clock face swaps left and right, moving the hour hand from the 3 position to the 9 position.
