📚 Quick Study Guide

  • 📐 Definition: A rectangle is a four-sided polygon (a quadrilateral) where all four angles are right angles (90 degrees).
  • 📏 Opposite Sides: Opposite sides of a rectangle are parallel and equal in length.
  • 🤝 Adjacent Sides: Adjacent sides (sides next to each other) are perpendicular, meaning they form a right angle.
  • diagonals are equal in length and bisect each other.
  • Area: The area of a rectangle is calculated by multiplying its length ($l$) by its width ($w$): $A = l \times w$.
  • 🧮 Perimeter: The perimeter of a rectangle is calculated by adding up all its sides: $P = 2l + 2w$ or $P = 2(l + w)$.
  • 💡 Key Features: Look for four sides, four right angles, and opposite sides that are equal.
