Geometry of Triangles - Scalene, Solve Angle (Level 1)

This math topic focuses on understanding the geometry of scalene triangles, specifically solving for unknown angles. It involves identifying given angles and selecting the correct value among multiple choices. Each question provides a diagram of a triangle with specific angles marked and asks participants to determine the information about a queried angle from several presented options. This is part of a broader unit on isosceles and equilateral triangles, intending to deepen understanding of triangle geometries and angle relationships.
