8. The corner points of a triangle where two sides meet. \( \begin{array}{ll}\text { A. Angles } & \text { C. Vertices } \\ \text { B. Sides } & \text { D. Congruence } \end{array} \)

The corner points of a triangle where two sides meet are known as vertices. Each triangle has three vertices, and they are typically labeled as points A, B, and C. These points are crucial for defining the shape and properties of the triangle, such as angles and side lengths. In real-world applications, knowing the characteristics of vertices can help in architecture and design. For instance, when planning a roof structure, the vertices determine how slopes will meet, affecting both stability and aesthetics. Understanding these concepts can lead to better construction practices and innovative building designs!
