Geometry of Triangles - Isosceles, Solve Side from Double Side (Level 1)

This math topic focuses on the geometry of isosceles triangles, specifically on how to solve for unknown sides given that one side is double another. It is aimed at developing skills in identifying and evaluating the properties of isosceles triangles. The topic includes multiple-choice questions that challenge the learner to determine the length of sides labeled 'R', 'S', and 'Q' based on given diagrams and geometric properties. Each question provides a set of possible numerical answers, enhancing problem-solving skills related to geometric reasoning and numerical calculation within the context of isosceles and equilateral triangles.
