Here is a glossary of key terms in geometry:

  • Point: A location in space that has no size, shape, or dimension. 🌟
  • Line: A straight path that extends infinitely in both directions.
  • Plane: A flat surface that extends infinitely in all directions.
  • Angle: The figure formed by two rays, or line segments, sharing a common endpoint.
  • Triangle: A polygon with three sides and three angles.
  • Square: A quadrilateral with four equal sides and four right angles.
  • Circle: The set of all points in a plane that are at a fixed distance from a given point called the center.
  • Radius: The distance from the center of a circle to any point on its circumference.
  • Diameter: The distance across a circle passing through its center.
  • Tangent: A line that touches a circle at only one point.
  • Chord: A line segment whose endpoints lie on a circle.
