Introduce and define the different types of triangles (equilateral, isosceles, scalene, acute, and obtuse).
Provide examples that demonstrate how to classify triangles by their angles and their side lengths.
Review how to name a triangle by its three vertices (ΔABC).
This packet should help a learner seeking to understand how to classify triangles by their sides and angles.
