  • Line segment (endpoints)
  • Ray (endpoint)
  • Angle (vertex, sides)
  • The length of a line segment
  • Acute angle
  • Right angle
  • Obtuse angle
  • Straight angle
  • Congruent segments (and associated symbology)
  • Congruent angles (and associated symbology)
  • Collinear points
  • Noncollinear points
  • Theorem
  • Segment bisector
  • Midpoint of a segment
  • Segment trisectors
  • Angle bisector
  • Angle trisectors
  • Postulate
  • Deductive structure
  • Conditional statements
  • Probability

Theorems

  • If two angles are right angles, then they are congruent (the right angle theorem or RAT)
  • If two angles are straight angles, then they are congruent
  • If a conditional statement is true, then its contrapositive is also true

Types of Problems

  • Determining unions and intersections in diagrams
  • Angle and triangle restrictions
  • Converting angle measures in degrees, minutes, seconds form to fractional form
  • Converting angle measures in fractional form to degrees, minutes, seconds form
  • Adding and subtracting angle measures in degrees, minutes, seconds form
  • Clock problems
  • Assumptions from diagrams (what can be assumed, what cannot be assumed)
  • Constructions
    • Segment bisector
    • Angle Bisector
    • Equilateral triangle (60° angle)
  • Transformations on the coordinate plane (90°, 180°, 270°, and reflection over y = x)
  • Symmetry (Rotational and Reflectional)
  • Determining the converse, inverse, contrapositive of conditional statements
  • Chain of reasoning
  • Simultaneous equations
  • Probability
