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

This math topic focuses on the geometry of equilateral triangles. Students are tasked with solving to find the lengths of sides labeled 'R', 'Q', and 'S' in various triangle diagrams. Each question is multiple-choice, with options presented for the students to choose the correct answer. The practice revolves around understanding the properties of equilateral triangles and applying that knowledge to solve problems for missing side lengths. This is part of a broader unit on isosceles and equilateral triangles.
