Understanding squares can make solving tricky problems in geometry a lot easier. This is because squares have some special features. Let’s look at some of these important points:

• Equal Sides: All four sides of a square are the same length. So, if one side is $s$, then all the sides are $s$ too.

• Angle Measures: Each angle in a square is $90^\circ$. This makes it simpler to figure out angles in problems.

• Diagonals: The diagonal lines in a square cross each other at right angles. They are also the same length, which is found using the formula $d = s\sqrt{2}$.

• Area Calculation: You can easily find the area of a square. Just use the formula $A = s^2$.

These features show why squares are so important. They help us understand more complicated shapes called quadrilaterals.
