Geometry of Triangles - Isosceles, Solve Angle from Single Angle (Level 2)

This math topic focuses on the geometry of isosceles triangles, where students solve for unknown angles given a single angle. It is part of a broader unit on isosceles and equilateral triangles. The problems present different scenarios involving isosceles triangles and require determining the measurements of specific angles from a set of options. Each problem challenges students to apply their understanding of the properties of isosceles triangles to find the correct angle measurements. This practice aims to develop skills in recognizing and solving geometric problems related to triangle properties.
