YES Symmetry Puzzle in Google Slides and PowerPoint

Written By Tony Vincent

Can you solve this symmetry puzzle? YES, yes you can!

I saw a physical puzzle with pieces that look like the letters Y , E, and S. The puzzle is available as a 3D printer file. The pieces can be arranged to form a shape that is symmetrical.

It’s somewhat easy to form a shape that is symmetrical using the Y and E since those shapes already have lines of symmetry.

I recreated the puzzle in Google Slides and PowerPoint. The first two slides introduce the puzzle, and the puzzle with movable pieces is on Slide 3.

Here are the instructions:

  • Arrange the Y, E, and S pieces in a way that has a line of symmetry running through it horizontally or vertically.

  • Each of the 3 pieces must be touching another piece with no overlaps.

  • Rotate pieces by 0, 90, 180, or 270 degrees.

  • Do not resize and do not duplicate any pieces.

  • After you think you’ve solved the puzzle, draw a blue line over your shape to show the line of symmetry.

The solution is on Slide 4 and can be revealed by deleting the rectangle that covers the answer. Teachers may want to delete Slide 4 before sending a copy to their students to control when the solution is revealed to the class.
