Expert verified

The result of this section illustrates that CD=DX.

Step by step solution

01

Step 1. Fold the sheet

Fold D onto BC so that the crease passes through C and unfold.

02

Step 2. Make the second fold

Fold A onto AD so that the crease passes through X as shown.

03

Step 3. Get the complete square.

Make the final fold to complete the square.

Above result shows that, DCX=45°, right angles ΔCDXhas equal base angles.

Therefore, CD=DX, as required.
