In the context of geometry, when dealing with rectangles like ABCD, several important theorems and properties can be referenced. Here are some key points:
1. **Properties of Rectangles**:
- Opposite sides are equal in length (AB = CD and AD = BC).
- All angles are right angles (90 degrees).
- The diagonals are equal in length (AC = BD).
- The diagonals bisect each other.
2. **Pythagorean Theorem**:
If you consider a rectangle ABCD, with sides \( AB \) and \( AD \) as the two legs, the length of the diagonal \( AC \) can be calculated using the Pythagorean theorem:
\[
AC = \sqrt{AB^2 + AD^2}
\]
3. **Area of a Rectangle**:
The area \( A \) of rectangle ABCD can be found using the formula:
\[
A = AB \times AD
\]
4. **Perimeter of a Rectangle**:
The perimeter \( P \) of rectangle ABCD is given by:
\[
P = 2(AB + AD)
\]
These properties provide a fundamental understanding of rectangles in geometry. If you have a specific theorem in mind or need clarification on a certain concept, please let me know!
