Nested Similar Triangles

Nested triangles have been created so that they share a common vertex and vertex angle. Learners drag the endpoints of the side that is opposite the common angle to discover the conditions that make the nested triangles similar. When learners make congruent angle marks appear, the triangles will be similar. Teacher notes and a PDF student activity are included along with a mini embedded video demonstration.
