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

This math topic focuses on the geometry of triangles, specifically solving for unknown sides in isosceles triangles. Students are presented with various triangle problems where they must determine the length of a given side based on given information about other sides of the triangle. Each question offers multiple choice answers, asking the learner to select the correct side length or state if the answer cannot be determined. This forms part of a larger unit on Isosceles and Equilateral Triangles, enhancing students’ understanding of triangle properties and their application in geometry.
