Geometry of Triangles - Scalene, Solve Side (Level 1)

This math topic focuses on determining the lengths of sides of scalene triangles, helping students practice solving geometric problems. Each question presents a diagram of a scalene triangle and asks what is known about a specific side, providing multiple choice answers. This topic is part of a broader unit on the geometry of isosceles and equilateral triangles. The skills practiced include interpreting geometric diagrams, applying triangle properties, and critical thinking in selecting possible side lengths based on given conditions.
