Tearing Tangrams

1. Start with a SQUARE. Fold it along the DIAGONAL. Crease and tear.

2. Take one of the ISOSCELES RIGHT TRIANGLES and position it so its HYPOTENUSE is its BASE. Fold it in half along the ALTITUDE and tear.

3. Take the large TRIANGLE. Find the midpoint of the hypotenuse and pinch. Fold the RIGHT ANGLE VERTEX down to touch the midpoint. Tear along the crease.

4. Fold the TRAPEZOID in half. Crease and tear.

5. Take one of the right trapezoids and place it so its longest side is at the base. Touch the right angle on the base to the OBTUSE ANGLE. Crease and tear.

6. Take the other right trapezoid and place it so its longest side is at the base. Touch the ACUTE ANGLE to the right angle on the base. Crease and tear.

7. Reassemble the SQUARE!
