Geometry of Triangles - Isosceles, Solve Side from Single Side (Level 2)

This math topic focuses on the geometry of isosceles triangles, specifically on determining the lengths of sides given limited information. It is part of a broader unit on isosceles and equilateral triangles. The problems require learners to use properties of isosceles triangles, such as equal sides and angles, to solve for unknown side lengths. Each question presents a diagram of a triangle with some side lengths labeled and asks what can be known about another side, providing multiple choice answers. These problems enhance understanding of triangle properties and problem-solving skills in geometry.
