Geometry of Triangle

These problems are designed to develop skills in solving for unknown angles in isosceles triangles, specifically identifying the values of specific angles given limited information. Each question contains a diagram of an isosceles triangle with one angle labeled, and students are tasked with determining the value of another angle. The answers are presented in multiple-choice format, aimed at reinforcing understanding of triangle properties, particularly the fact that isosceles triangles have two angles that are equal. This topic is a part of a broader unit on geometry dealing with isosceles and equilateral triangles.
