This digital resource focuses on types of triangle congruence: SSS, SAS, ASA, and AAS. Fifteen images are provided, and students have to determine if they're congruent, and if so, through which method. Three of each type are provided. My favorite part is that it is self-grading! This resource works great as a quiz, a do now, a classwork assignment after teaching the lesson, or as a homework assignment. Font Credit: RY Fonts
