This math topic focuses on understanding the properties of equilateral triangles and solving for their angles. It provides practice in determining specific angles within equilateral triangles. Each problem presents a figure of an equilateral triangle with named vertices (such as 'R', 'Q', 'S') and asks the student to identify the measure of a particular angle from multiple-choice options. This set of problems is part of a broader unit on the geometry of isosceles and equilateral triangles, aimed at developing foundational skills in triangle geometry.
