About This MicroSim

This practice tool presents triangle pairs with various congruent parts marked. Your task is to identify which congruence criterion (if any) applies.

How to Use

  1. Examine the triangles and the marked congruent parts
  2. Click an answer (SSS, SAS, ASA, AAS, HL, or Not Enough)
  3. Click "Check Answer" to see if you're correct
  4. Click "Next Problem" to continue practicing
  5. Click "Hint" if you need help

Answer Choices

Choice Meaning
SSS Three sides congruent
SAS Two sides + included angle
ASA Two angles + included side
AAS Two angles + non-included side
HL Right triangle: hypotenuse + leg
Not Enough Information insufficient (like AAA)

Visual Markers

  • Orange tick marks on sides indicate congruent sides
  • Purple arcs at angles indicate congruent angles
  • Red square indicates a right angle

Learning Objectives

  • Apply triangle congruence criteria
  • Analyze which criterion fits given markings
  • Evaluate whether information is sufficient
