  • Angle
    Space formed between two line segments, measured in degrees, representing the gap created at their intersection.
  • Degree
    Unit for measuring the size of an angle, ranging from 0 to 360, based on ancient conventions for circles.
  • X-Y Coordinate System
    Grid with horizontal and vertical axes used to sketch and measure angles from a fixed starting point.
  • Initial Side
    Reference line for drawing angles, always placed along the positive horizontal axis in standard sketches.
  • Terminal Side
    Second line segment that defines the angle's extent, positioned away from the reference axis.
  • Standard Position
    Convention for sketching angles with the reference side on the positive horizontal axis and measuring from there.
  • Positive Angle
    Angle measured counterclockwise from the reference axis, following the established mathematical convention.
  • Negative Angle
    Angle measured clockwise from the reference axis, indicating a direction opposite to positive angles.
  • Acute Angle
    Type of angle with a measure less than 90 degrees, often appearing in sketches and classifications.
  • Obtuse Angle
    Type of angle with a measure greater than 90 degrees but less than 180 degrees, used in classification.
  • Right Angle
    Type of angle with a measure exactly equal to 90 degrees, forming a perfect quarter turn.
  • Quadrant
    Section of the coordinate grid, each spanning 90 degrees, used to locate and sketch angles.
  • Protractor
    Instrument for estimating and drawing angles, helpful for visualizing degree measures on sketches.
