Two or more points are if they lie on the same line. A. rays B. segments c. complementary D. collinear

Did you know that the term "collinear" comes from the Latin words "col" meaning "together" and "linea" meaning "line"? This concept is fundamental in geometry, helping us describe points that are aligned on a single straight path, like a row of ducks marching in a straight line! In real-world applications, understanding collinearity is crucial in fields such as architecture and computer graphics. For instance, when designing an architectural layout, ensuring that certain points are collinear can help maintain the structure's aesthetic line and prevent it from looking off-kilter or misaligned.
