What to Focus On
- Doubling the side of a square makes the area 4 times, not 2 times.
- The diagonal of a square can be used to construct a square of double area.
- For a unit square, the square on the diagonal has area 2 sq. units.
- Half the side length gives one-fourth the area, not half.
- Folding through the midpoints gives a smaller square with half the area.
- PQRS is the square formed in the folding construction.
- The side opposite the right angle is the hypotenuse.
- For the unit isosceles right triangle, c^2 = 2 and c = √2.
- 1 < √2 < 2.
Common Mistakes to Avoid
Doubling the side length of a square doubles its area.
The square with half the side length has half the area.
The diagonal of a square is just another side of the square, so it has the same length as the side.
