The document discusses different types of triangles: equilateral triangles have 3 congruent sides and 3 congruent angles of 60 degrees each. Isosceles triangles have 2 congruent sides and 2 congruent angles. Scalene triangles have no congruent sides or angles. It notes the relationship between angles and opposite sides - the smallest angle is opposite the smallest side, and the largest angle is opposite the longest side. Several examples are given to demonstrate naming sides and angles from smallest to largest. It also discusses how the sum of two angles must be less than the third angle.
