NNAT Mirror Images and Rotations

Question 1

When a figure is reflected in a vertical mirror, which aspect changes?

Accepted Answer

Left and right are reversed

Answer

A vertical mirror line reverses the left-right orientation while keeping everything else the same.

Question 2

A letter F is rotated 180 degrees. What does it look like?

Accepted Answer

An upside-down and backwards F

Answer

A 180-degree rotation turns the figure completely upside down and reverses its horizontal direction.

Question 3

How do you distinguish between a rotation and a reflection of a figure?

Accepted Answer

A rotation preserves the same orientation (handedness); a reflection reverses it

Answer

A key difference is that rotation preserves handedness (a clock stays clockwise) while reflection reverses it (a clock becomes counter-clockwise).

Question 4

If a triangle pointing right is rotated 90 degrees clockwise, which direction does it point?

Accepted Answer

Down

Answer

A 90-degree clockwise rotation moves the pointing direction one quarter turn to the right: right becomes down.

Question 5

A figure has rotational symmetry of order 4. What does this mean?

Accepted Answer

It looks the same after rotations of 90, 180, 270, and 360 degrees

Answer

Order 4 rotational symmetry means the figure maps onto itself 4 times during a full 360-degree rotation (at 90° intervals).
