Determining Similarity of Triangles by Examining Corresponding Parts

This lesson teaches how to determine if two triangles are similar by examining their corresponding parts. It covers similarity transformations such as translation, reflection, rotation, and dilation, and explains how these transformations affect the shape and size of polygons. The lesson also discusses the properties of similar triangles, including proportional sides and congruent angles. An example is provided to demonstrate how to determine similarity using parallel lines and angle congruence. The lesson concludes by affirming that knowing three pairs of congruent angles is sufficient to establish triangle similarity.
