Free Math Interactive | Congruence Theorem

Free Math Interactive | Congruence Theorem -This high school level math interactive was developed to get students to explore conditions that result in congruent triangles. Based on a previous applet that was available on the NCTM Illuminations website, our team was asked to redesign and make the interaction of this applet more user-friendly and intuitive.
