What is 11 squares?

1. A square is a geometric shape that has four sides of equal length and four right angles.
2. The area of a square is calculated by multiplying the length of one side by itself (squared).
3. The perimeter of a square is calculated by adding the length of all four sides together.
4. In a unit square, each side measures one unit of length, and the area is also one square unit.
5. A square can be divided into four congruent right triangles.
6. The diagonal of a square divides it into two congruent isoceles right triangles.
7. The sum of the measures of the interior angles of a square is 360 degrees.
8. Perimeter of a square = 4 x length of one side.
9. The Pythagorean theorem, a^2 + b^2 = c^2, can be used to find the length of the diagonal of a square if the side length is known.
10. The regular polygons with the greatest number of sides that can be inscribed in a unit square are octagons, with eight sides.
11. Squares can be found in many real-life objects, such as tiles, windows, and computer screens.
