Study Notes

Geometry

  • Deals with the study of shapes, sizes, and positions of objects
  • Involves understanding and working with different types of geometric objects, such as points, lines, angles, and planes

Point

  • A location in space, represented by a set of coordinates (x, y, z)
  • Has no size or dimension, only a position
  • Denoted by a capital letter (e.g. A, B, C)

Line

  • A set of points that extend infinitely in two directions
  • Can be named by two points on the line (e.g. AB)
  • Can be represented by the equation y = mx + b, where m is the slope and b is the y-intercept

Line Segments

  • A part of a line with a fixed length and two endpoints
  • Has a definite length and can be measured
  • Denoted by a bar over the letters of the endpoints (e.g. AB̄)

Ray

  • A line that extends infinitely in one direction from a single point
  • Has a starting point, but no endpoint
  • Denoted by an arrow over the letters of the starting point and another point on the ray (e.g. →AB)

Angles

  • Formed by two rays sharing a common endpoint (called the vertex)
  • Measured in degrees, with 360 degrees in a full circle
  • Types of angles:
    • Acute angle: less than 90 degrees
    • Right angle: exactly 90 degrees
    • Obtuse angle: greater than 90 degrees but less than 180 degrees
    • Straight angle: exactly 180 degrees
    • Reflex angle: greater than 180 degrees but less than 360 degrees

Geometry

  • Studies the properties and relationships of shapes, sizes, and positions of objects

Geometric Objects

  • Points: locations in space with no size or dimension, only a position
  • Lines: sets of points extending infinitely in two directions
  • Angles: formed by two rays sharing a common endpoint (vertex)
  • Planes: flat surfaces extending infinitely in all directions

Points

  • Represented by a set of coordinates (x, y, z)
  • Denoted by a capital letter (e.g. A, B, C)
  • No size or dimension, only a position

Lines

  • Can be named by two points on the line (e.g. AB)
  • Can be represented by the equation y = mx + b, where m is the slope and b is the y-intercept
  • Extend infinitely in two directions

Line Segments

  • Part of a line with a fixed length and two endpoints
  • Has a definite length and can be measured
  • Denoted by a bar over the letters of the endpoints (e.g. AB̄)

Rays

  • Line that extends infinitely in one direction from a single point
  • Has a starting point, but no endpoint
  • Denoted by an arrow over the letters of the starting point and another point on the ray (e.g. →AB)

Angles

  • Measured in degrees, with 360 degrees in a full circle
  • Types of angles:
    • Acute angle: less than 90 degrees
    • Right angle: exactly 90 degrees
    • Obtuse angle: greater than 90 degrees but less than 180 degrees
    • Straight angle: exactly 180 degrees
    • Reflex angle: greater than 180 degrees but less than 360 degrees
