While exploring an ancient forest path, Emek and Luna discovered stone symbols carved beside each fork in the trail. Every marker matched a nearby carving only after a single geometric transformation. At one stop, they translated a symbol to line up with engraved guide marks. At the next, they recognized that a 90° rotation produced the correct orientation, and later they identified a reflection across a marked line. By selecting the correct transformation at each marker, they revealed the next trail sign and safely reached a hidden woodland sanctuary.

Hint
Look for the transformation that changes the figure's orientation without changing its size.
At one marker, Emek found that the carved symbol matched the guide only after a 90° rotation. Which transformation was needed?
TranslationReflection90° rotationEnlargementCorrect! A 90° rotation changes the orientation while preserving the figure.
Try again. A translation slides a figure, while a rotation turns it.

Hint
Add the angles of the two rotations.
A symbol is rotated 90° clockwise two times in a row. Through how many degrees has the symbol rotated altogether?
Correct! Two 90° rotations make a total rotation of 180°.
Check the total angle after performing two 90° rotations.

Hint
A mirror image is created by reflecting a figure across a line.
At the final trail marker, the carving became a mirror image across a marked line. Which geometric transformation did Emek and Luna use?
TranslationReflection90° rotationShearCorrect! A reflection produces a mirror image across a line.
Try again. Think about which transformation creates a mirror image.
