    ๐Ÿ“
  • Point: A point is an exact location in space. It has no size, only position. We represent it with a dot.
  • ๐Ÿ“
  • Line: A line is a straight path that extends infinitely in both directions. It has no endpoints. We denote it with arrows on both ends.
  • โž–
  • Line Segment: A line segment is a part of a line that has two endpoints.
  • โ˜€๏ธ
  • Ray: A ray is a part of a line that has one endpoint and extends infinitely in one direction.
  • ๐Ÿ“
  • Angles: Formed by two rays sharing a common endpoint (vertex). Measured in degrees.
  • โ†”๏ธ
  • Parallel Lines: Lines in a plane that never intersect.
  • โž•
  • Perpendicular Lines: Lines that intersect at a right angle ($90^{\circ}$).
