A square is a special type of quadrilateral, which is a polygon with four sides. What sets a square apart from other quadrilaterals is that all four of its sides are equal in length, and all four of its angles are right angles (90 degrees).

1. **Equal sides:** All four sides of a square are of equal length. This means if one side is 's', then all sides are 's'.

2. **Right angles:** All four angles of a square are right angles (90 degrees).

3. **Diagonals:** The diagonals of a square are equal in length and bisect each other at right angles.

4. **Perimeter:** The perimeter of a square is four times the length of one of its sides, so if the length of a side is 's', then the perimeter is 4s.

5. **Area:** The area of a square is the length of one of its sides squared, so if the length of a side is 's', then the area is s^{2}.

Perimeter = 4 × side length (P = 4s)

Area = side length × side length (A = s^{2})

To understand squares better, make sure to focus on the following:

- Understand the definition of a square and its properties.
- Learn how to calculate the perimeter and area of a square using the formulas provided.
- Practice identifying squares and their properties in everyday objects and shapes.
- Work on solving problems involving squares to solidify your understanding.

Remember to ask your teacher or tutor for help if you have any difficulties with understanding squares and their properties.
